Installation & Start Up
Installation of the LabTec™ System must be carried out only by trained personnel in accordance with
the relevant regulations and this operations manual.
Make sure that the technical specifications and input ratings of the LabTec™ are observed.
See “LabTec™ Specifications”.
The protection provided by this equipment may be impaired if the LabTec™ is used in a manner
inconsistent with this manual or for purposes not specified by the manufacturer.
Maintenance & Cleaning
The LabTec™ is practically maintenance free. The SciPres® sensors used with the system come
pre-calibrated from the factory and require no maintenance. The ™ peristaltic pump head should
periodically have tubing debris cleaned from it, but requires no lubrication.
Parker recommends a factory cleaning, testing and recalibration be done to your LabTec™ at least
once a year, to maintain the accuracy of the unit and reduce your downtime.
Contact Customer Service for an RGA or contact your Territory Manager. We can design a
preventative maintenance program specifically for your company.
To remove dust, dirt and stains, the outer surfaces of the LabTec™ may be wiped using a soft,
non-fluffing cloth moistened with water. If required, you may also use a mild detergent or 2-propanol.
The SciPres® sensors may be sanitized with 0.1 Molar NaOH, or 2-propanol. They may be autoclaved
up to twice, and may be gamma-irradiated.

3.
At this point, you need to consider the parameters of the dispensing that you are going to do.
The following is a list of the various parameters available, and their defaults. We strongly suggest
that you use #24 Silicone tubing and these defaults initially, and then optimize your system after a
review of your results during the first few days of operation.
WGT FACTOR: Defines the weight ratio (multiplier) that is applied to the actual sample weight, as
determined by the scale, to arrive at the required diluent weight. WGT FACTOR = 9.00 is the default,
and will yield a 10-fold dilution. You may increase or decrease this to any ratio desired. Select a
WGT FACTOR = 99.00 if you want a 100-fold dilution.
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle to
suck in the droplet that typically hangs at the end of the dispensing tip. When a filter is in use it will
relieve the pressure so it does not drip. Select SNIFFLE = 0.3. (The default is 0.0.)
SLOW FACTOR: Defines the diluent weight that is dispensed slowly at the end of the dispensing
cycle.The default SLOW FACTOR = 25.0 grams. This may be adjusted if necessary.
DIRECTION: Defines the rotation of the pump head. This parameter can be changed from clockwise
(CW) to counter clock-wise (CCW). (Default = CW)
PUMP RATE: Defines the relative pup speed (0% to 100%) with which the diluent is being
dispensed. The default PUMP RATE = 80%. This may be adjusted as needed. Higher speeds are
not recommended.
TIME DELAY: Not used in We i g h t Ratio Dispensing mode. Defines the time interval , in seco nd s,
between dispensing cycles. (Default = 00.01)
COUNT: Not used in Weight Ratio Dispensing mode. Defines how often the dispensing cycle will
be repeated. For example, when COUNT = 10, then the selected DISP. WEIGHT will be dispensed 10
times. (Default = 1)

SW stands for the actual sample weight and DW represents the delivered diluent weight.
When the dispensing cycle is completed, following displays are shown.
DISPENSING
Completed
Remove the filled sample bag or container and initiate the next dispensing cycle.
Note: If you have more than one WGT FACTOR, store one WGT FACTOR i n “E d it 1 ” , e .g .
“9.00”, while a second WGT FACTOR is stored in “Edit 2”, e.g. “99.00”. Up to ten different
sets of parameters can be stored in “Edit 1” through “Edit 10”.
Note: The following may affect your accuracy, and should be considered:
1.
Parker suggests you use #24 tubing, and move the portion inside the pump 3-4 inches toward
the discharge side of the pump periodically to avoid wearing it out. As the
tubing becomes
worn, your dilutions may take longer, and you may get debris in the diluent.
#35 tubing can cause target weight overruns, and is generally considered to be too large for
this application.
2.
Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur after
the dilution, thereby eliminating overruns. These procedures suggest an initial factor
of 0.3. If you are using a filter, this may need to be increased as the filter becomes plugged.
3.
Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. Increasing the Slow Factor will help if your scale response time
is long, and decreasing the Pump Rate will help if the default of 80% is causing too much
backsplash that can’t be eliminated in some other manner. The settings cited work best
with a Mettler Toledo model scale.

6. Route the remaining tubing to the solution reservoir and attach it as appropriate.
Note: If you purchased the LabTec™ with your aliquot sizes preprogrammed by Parker the
calibrations have been done for you. If this is not the case, or you have performed a
Reset, you will need to edit the individual aliquots (Edit 1-10) as shown below.

Page 17
Calibration:
1. The LabTec™ will come configured for the installed motor and pump head. This example will
assume a 600 rpm motor and a ™ 1082 head is installed. If you have a different head,
please refer to the manual or contact Parker for assistance. Each EDIT
a choice of tubing, and then accesses built-in master calibration curves.
In addition to adjustments to the motor speed and slow factor, fine tuning of the calibration
is accomplished by using the Re-Cal feature accessible directly from the “RE-CAL” button on
the front of the LabTec™.
(1 – 10) allows
2. The RE-CAL feature is accessible from the keypad of the LabTec™ using the “RE-CAL” button
located in the lower right-hand corner. To do this accurately, it is important that you have a
scale available to dispense the aliquot onto that has a readability of 0.1 gm or better.
A graduated cylinder may also be used. This feature is active when the following type of
display is shown:
VOLUME SET: 10:00 mL
Press RUN when Ready
3. After checking to be sure that the system is primed, Press the RUN key and dispense 10.00 mL
into the container on the scale. Record the weight, and do this for a minimum of 3 times, and
determine the average (AV) aliquot weight. For example, assume you obtained the following
values:
Trial 1 10.25 gm
Trial 2 10.30 gm
Trial 3 10.20 gm
AV = Average Value 10.25 gm
4. Press the “RE-CAL” key on the front panel of the LabTec™, and the following display
will appear:
DV = 10:00
Incr.
A B C
Decr.
AV = 10:00
Select
5. Only the AV parameter can be changed in this display, use the “A” and “B” keys to adjust the
value. In the above example, you would increase the AV value to 10.25. Press the “C” key to
Select and the stored calibration curve will be updated. You may wish to repeat the RE-CAL as
necessary for improved dispensing accuracy.
6. This procedure is performed after all of the EDIT parameters explained below have been
entered into the LabTec™ for that particular aliquot.
17
Page 18
Program Editing and Execution
At this point, you need to consider the parameters of the dispensing that you are going to do. The
following is a list of the various parameters available, and their defaults. Adjust these parameters
based on the volume that you are dispensing.
DISPENSE VOLUME: Defines the volume to be dispensed in milliliters. (The default volume is 10.0
mL).
PUMP TUBING: This choice exists if a peristaltic head has been installed. Choices are 13, 14, 16,
25, 17, 18, (thin-walled, 1081 Head) 15, 24, 35 (thick-walled, 1082 Head). The built in master
calibration for that tubing is then utilized. (Default = 13)
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle
to suck in the droplet that typically hangs at the end of the dispensing tip. It also will relieve the
pressure on a filter if you are using one so that it does not drip. (The default Sniffle = 0.3, please
start at 0.0 if not using a filter.)
SLOW FACTOR: Defines the solution volume that is dispensed slowly at the end of the dispensing
cycle. This should be set between 1-10 mL depending the volume being dispensed and the tubing
size to avoid overshooting the target volume. For example, if you’re using #15 tubing, and the target
volume is 100 mL, a slow factor of 1 or 2 mL will work fine. The default Slow Factor = 1.00 mL. This
may be adjusted as necessary.
DIRECTION: Defines the rotation of the pump head, this parameter can be changed from clockwise
(CW) to counter clock-wise (CCW). (Default = CW).
PUMP RATE: Defines the relative pump speed (0% to 100%) with which the solution is being
dispensed. The default Pump Rate = 100%. This may be adjusted as needed, slower pump rates
may be desirable to increase precision and minimize back splashing.
TIME DELAY: Defines the time interval, in seconds, between dispensing cycles. (Default = 1.0).
COUNT: Defines how often the dispensing cycle will be repeated. For example, when COUNT = 10,
then the selected Dispense Volume will be dispensed 10 times. (Default = 1).
1. For this example, the tubing will be #24, and a dispense volume of 100.00 mL. From the Mode
Select screen, use “A” or “B” to go up or down to the “Volume” mode, and Press “C” to select it.
The Volume mode will give you the following display.

P1=0.0
Where DV=Dispensed Volume, CV=Cumulative Volume, SC=Sample Count # for the volume
dispensed, will increment by one for each occurrence, and P1=Back Pressure (will be 0.0 if
no pressure sensor is in use). The display will then alternate between this screen and the one
before it.
8.
At this time it is appropriate to use the RE-CAL procedure mentioned in the earlier Calibration
section to fine tune the process. Once satisfied with the results, you can continue pressing the
run key until you have finished the needed number of aliquots.
19
Page 20
Documentation
The LabTec™ will output data to a printer or a PC at the completion of each dispense for archival
purposes. The following is an example of that data, and the abbreviations used.
1. Parker suggests you use #15 or 24 tubing, and move the portion inside the pump 3-4
inches toward the discharge side of the pump periodically to avoid excessive
wear. As the
tubing becomes worn, you will want to run the RE-CAL feature again.
#35 tubing will allow you to pump at higher flow rates, but a larger slow factor should
be implemented.
2. Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur
after dispensing, thereby eliminating overruns. These procedures suggest an initial factor
of 0.0. If you are using a filter, this may need to be increased as the filter becomes plugged.
3. Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. The Slow Factor should be set to 1 or 2 mL for most tubing, and
up to as much as 5 mL if you are using large diameter tubing. Decreasing the Pump Rate
will help if the default of 100% is causing too much backsplash that can’t be eliminated in
some other manner, or if the dispense volume is small.

Program Editing and Execution
At this point, you need to consider the parameters of the dispensing that you are going to do. The
following is a list of the various parameters available, and their defaults. Adjust these parameters
based on the weight that you are dispensing. Consult Part C, Section 5.0, of the LabTec™ Manual to
edit your weight dispensing parameters.
DISP. WEIGHT: Defines the weight to be dispensed in grams. F or exampl e, if you want to dispense
50.00 grams, use the “Incr” and “Decr” keys to scroll to 50.00 and press “Select”. (The default
Disp. Weght = 100.00 gm).
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle to
suck in the droplet that typically hangs at the end of the dispensing tip if a filter is used by reducing
the back pressure. Select Sniffle = 0.0 (Adjust as needed if a filter is used).
SLOW FACTOR: Defines the solution weight that is dispensed slowly at the end of the dispensing
cycle to allow for stabilization of the scale. This should be 10-15% of the total weight if the aliquot
is less than 50 gm. For aliquots larger than 50 gm, the default of 25 gm will usually work well. This
can be adjusted based on the pump rate and the tubing size to avoid overshooting the target weight.
(The default Slow Factor = 25 gm).
DIRECTION: Defines the rotation of the pump head, this parameter can be changed from clockwise
(CW) to counter clock-wise (CCW). (Default = CW).
PUMP RATE: Defines the relative pump speed (0% to 100%) with which the solution is being
dispensed. The default Pump Rate = 80%. This may be adjusted as needed. Slower pump rates
may be desirable to increase accuracy and minimize back splashing.
TIME DELAY: Defines the time interval, in seconds, between dispensing cycles. (Default = 00.01).
COUNT: Defines how often the dispensing cycle will be repeated. For example, when COUNT = 10,
then the selected Dispense Weight will be dispensed 10 times. (Default = 1).
1. For this example, set a dispense weight of 200.00 gm. From the Mode Select screen, use “A”
or “B” to go up or down to the “Weight” mode, and Press “C” to se le ct it . T he We ig ht m od e w il l

Documentation
The LabTec™ will output data to a printer or a PC at the completion of each dispense for archival
purposes. The following is an example of that data, and the abbreviations used.
Note: The following may affect your accuracy, and should be considered:
1. Parker suggests you use #15 or 24 tubing, and move the portion inside the pump 3-4
inches toward the discharge side of the pump periodically to avoid excessive
wear. #35 tubing will allow you to pump at higher flow rates, but a larger slow factor should
be implemented.
2. Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur
after dispensing, thereby eliminating overruns when a filter is used. These procedures
suggest an initial factor of 0.0. If you are using a filter, this may need to be increased as the
filter becomes plugged.
3. Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. The Slow Factor should be set to 25 gm for most aliquots, and
adjusted up or down based on aliquot size and scale response time. Increasing it beyond
40 gm will just slow down your dispense times without a corresponding increase in
accuracy. Decreasing the Pump Rate will help if the default of 80% is causing too
much backsplash that can’t be eliminated in some other manner, or if the dispense
weight is small.
4. When executing the “Weight Dispense” cycle, the pump begins at the specified pump rate.
The LabTec™ will slow down during the last 25 gm (as defined by the “Slow Factor”) to avoid
overshooting the target weight. After dispensing 98% of the target weight, the LabTec™
stops momentarily. At this point, the scale will reach a steady state, and the LabTec™ will
calculate the precise amount needed to reach the target weight. If the LabTec™ does not
stop at the 98% of target weight point, it will have overshot the target weight. Either
increase the”Slow Factor”, or decrease the chosen “Pump Rate” so that the pump
performs in this manner.

Part A: LabTec™ Hardware:
1.0 Hardware Overview
The LabTec™ has been designed to automate batch-dispensing of liquids from the low milliliter
(0.5 mL) to liter range. The LabTec™ allows you to optimize the dispensing rate per aliquot as well as
the dispensing precision and accuracy, while monitoring pressure if a fi er is in use. A high pressure
alarm may be set to stop the pump when a user-defined value has been achieved. The LabTec™
can be used for either sterile or non-sterile dispensing applications as well as for aqueous and
nonaqueous batch dispensing.
In automated batch dispensing, three (3) important parameters, namely, dispensing rate, precision
and dispensing accuracy need to be considered. The LabTec™ has typical precision and accuracy
levels consistently in the 0.3% to 1.0% range; however the actual precision and accuracy levels are
somewhat dependent on the dispensing speed or pump rate.
In general, the higher the dispensing rate is, the poorer the dispensing precision and accuracy will
be. Conversely, the dispensing precision and accuracy generally will improve with lowering of the
pumping rate.
The two-channel Tandem™ 1081 peristaltic pump head can accommodate PharMed and
Platinum-cured Silicone pump tubing, sizes 13, 14, 16, 25, 17 & 18. If equipped with the ™ 1082
model, sizes 15, 24 & 35 can be accommodated. All pump tube sizes are factory calibrated, however,
the user can easily recalibrate any tube size with a single keystroke from the LabTec® front panel in
Constant Rate mode.
The ™ pump head delivers fl w rates ranging from 0.03 mL / min. to 2200 mL / min. for each of the
two pump channels depending on motor rpm. Two pump heads can be mounted together to provide a
four-channel pumping capability, and drastic reduction in pulsation when two upper or lower
channels are combined into one with appropriate Y-type connectors.
Note: The LabTec™ usually is configured with a 600-rpm motor and one of the aforementioned
pump heads. However, if your dispensing needs require, the LabTec™ is available with piston
or magnetic gear pump heads and appropriate motors that work well for both aqueous and
non-aqueous solutions.
26
Page 27
2.0 Front Panel: Data Entry & Display
The front panel consists of a user interface, which includes an alphanumeric display and a
membrane keypad to select operational modes and alarm settings. The display is a two line,
20 character each, liquid crystal display (LCD). The display is backlit to allow easy viewing over a
wide range of lighting conditions.
The lower line on the LCD is used to signify the function of the “soft keys” marked “A”, “B” and “C”.
The “soft key” current labels are displayed in the lower line of the LCD. If you press these keys, then
the function displayed above it will be performed.
The main keypad consists of eight “hard” keys whose function does not change. These keys are used
for basic control and programming of the LabTec™.
Executes the selected operational mode and starts pump.
Interrupts current operational mode and stops pump.
This button acts as a “shortcut’ key to change the amount dispensed without
exiting the dispensing mode. Use in Manual mode to change the motor speed.
This is used to prime the tubing. It is a momentary switch and only runs the motor
while it is depressed.
Another shortcut key used to change the number of sequential dispenses without
leaving the dispensing mode.
Another shortcut key used in conjunction with Count above to set the delay time
between sequential dispenses without leaving the dispensing mode.
Used to Exit the current operational mode or menu level, stops pump.
Used for re-calibration of the dispensed amount in Volume Dispense Mode.
Two LED’s are also on the front panel, just to the left of the main keypad.
These indicate the current pump status. A green light indicated the pump is in motion;
the red light indicated that the pump has stopped.

4.0 ™ Dual Channel Peristaltic Pump Head
The peristaltic pump head is specifically designed for use with the LabTec™ system.
The Parker pump heads (models 1082 & 1081) will provide you with rugged reliabili- ty as long as
common sense maintenance and good quality pump tubing are used. For most dispensapplications, you should be using the 1082 (P/N: 080-1082) together with either #24 or #15(thickwalled) silicone pump tubing.
For most dispensing application in the 10 mL to 500 mL range the 1082 (P/N: 080-1082) together with
thick-walled, #24 silicone tubing is the most appropriate and useful pump head / tubing combination.
Use #15 thick-walled silicone pump tubing for dispensing applications in the 2.5 to 10 mL range.
For dispensing applications below 2.5 mL, the 1081 (P/N: 080-108) together with thin-walled tube
sizes (#13, 14, 16) is the most appropriate pump head / tubing combination.
The pump head is typically driven by a 600 RPM, high-torque motor. The pump motor is
optically encoded and servo-controlled, thus the pump head will maintain a constant output over a
wide range of dispensing conditions.
However, when the pump head requires excessive torque because of pump tube failure or
“freezing” of the pump head, then the LabTec™ control software will recognize this condition and go
into a stand-by mode, the pump motor is turned off and the following message is displayed:
ing
CHECK PUMP HEAD
Press Any Key
Before continuing with your pumping application, remove the defective pump head / tubing and either
clean or replace with a functional pump head. This feature (PumpSense™) has been implemented by
Parker to protect your pump motor and electronics.
Note: There is nothing wrong with the LabTec™ controller when you see this display. The problem
lies with the pump head and / or pump tubing you are using. When you “Press Any Key” to leave
the stand-by mode, you will return to the previous Menu. After you check and replaced your pump
head / tubing, you may re-initialize your application.

Pump Head Installation
1. Identify the front and back of the . Two 8-32 mounting cap screws, as well as the
pump shaft tang that extends from the back of the pump head.
2. Facing the front of the , open the pump head by moving the black lever 180° to the
left. The upper and lower pump shoe will move in opposite directions, thereby exposing the
inside of the upper and lower pump shoe channels.
3. With the pump head completely opened, locate the mounting holes for the two
8-32 cap screws inside the lower pump channel.
4. On the front panel of the LabTec™, locate the mounting holes and the slotted pump head
coupler.
5. Before fastening them, align the two mounting screws and pump shaft tang of
the
with the holes and slotted coupler of the LabTec™ front panel mounting
plate.
The tang should have a grey plastic piece pressed on its end.
6. Make sure the pump shaft tang is properly seated in the mating slot of the pump
head coupler, before fastening the to the front panel of the LabTec™.
4.2 Peristaltic Pump Tubing / Rate Selection
For most sterile, liquid dispensing applications larger than 10.00 mL, the 1082 together
with thick-walled, #24 pump tubing is the most useful pump head / tube combination.
For dispensing applications in the 2.5 mL to 10 mL range, the 1082 together with
#15 thick-walled-walled pump tubing is the most useful pump head / tubing combination.
The following chart lists the nominal flow rates of the available motor / tubing combinations:
Note: Differences in pump tube formulation / manufacture, as well as pump tube wear over time
may cause the LabTec™ pump output to change. Thus for very high pump rate accuracy you may
want to re-calibrate the LabTec™ with your particular pump tubing in place. Recalibration of the
LabTec™ pump is very easy and straight forward.
32
Page 33
4.3
Pump Tube Installation
Note: Do NOT mount or dismount the pump head while the LabTec™ is powered. Do NOT
change pump tubing while the LabTec™ is powered. When using both upper
and lower pump channels simultaneously, the same type of tubing should be used in
each channel.
1. Open the pump head by moving the black loading lever 180° to the left. If you are going to use
the upper pump channel, slip the tubing into the upper channel; this is over the pump roller
cage. If the lower pump channel is used, feed the tubing through the lower
channel; this is under the pump roller cage.
2. Lock the tubing in place by pushing the loading lever 180° to the right. The tube retainer spring
will automatically place the correct tension on the pump tubing to prevent tube “walking”.
3. With the pump head closed, lightly pull the two ends of the tubing in opposite
directions and away from the pump head. This pulling action insures that the pump tubing is
taut and within the pump channel.
4.4 Pump Tube Replacement
1. The pump tubing section located in the pump head should be advanced at regular time intervals, i.e.: daily, if the LabTec™ is heavily used.
2. When advancing pump tubing, the used pump tube section must be moved to the pump
discharge side, i.e. dispensing side. The used pump tube section is weakened and tends to
collapse when placed on the suction side of pump head.
3. When you advance or replace the pump tubing, break-in the new pump tube section by letting
the pump run for a few minutes before attempting RE-CAL. The pump output will have
stabilized during the break-in period, thus your calibration will be more accurate.
33
Page 34
5.0 Magnetic Gear Pump Head: Model 201
The LabTec™ with a Magnetic Gear Pump Head is recommended for large-volume dispensing
applications. Used mainly for dispensing clean organic solvents. This is not considered a sterile
pump head.
The Model 201 magnetic gear pump head is an external type gear pump, which produces a pulse-less
flow. The spur gears rotate and intermesh inside the pumping chamber, thereby creating a pressure
differential between the inlet and outlet of the pump.
Note: An in-line check valve (P/N: 400-530) must be installed on the discharge side of the pump
head in order to avoid back-siphoning of solution between dispensing cycles and avoid losing
prime by allowing the pump head to remain dry. Make sure that the dispensing tip is located
above the solution reservoir level.
The rotating gears of the magnetic gear pump head generate significant shear, thus shear-sensitive
solutions, i.e. enzyme or protein preps, should be dispensed with the peristaltic pump.
Only clean fluids, without particulates or abrasives should be dispensed with magnetic gear pump
heads. Any particulates or abrasives will rapidly wear down the rotating gears and will decrease
pumping capacity. A gear replacement kit for the 201 (P/N: 080-320) is available from Parker.
Note: Dispensing liquids with a viscosity greater than 1000 centipoises should be avoided.
Such high viscosity can cause magnetic de-coupling of the pump head. Reduce the LabTec™
pump speed when dispensing fluids with viscosity greater than 300 centipoises.
Magnetic de-coupling occurs when the torque limit of the driving magnet has been exceeded.
Once de-coupling occurs, the driving magnet (this is the magnet fastened to the motor shaft) turns by
itself while the driven magnet (inside the pump head) is motionless. The Magnets will automatically
re-align and re-couple when the motor stops.
Important: When your dispensing task is completed, flush distilled water or an appropriate
solvent through the pump head for approximately two (2) minutes or until the solution appears
clear. Do not leave the dispensing solution in the pump head overnight.
Mag 122, 120, and 040 heads are also available if slower flow rates are required, the same comments
above apply.

6.0 FMI Piston Pump Heads: General Information
The LabTec™ FM-200 and FM-520 pumps use rotating, reciprocating piston pump heads of various
sizes. In this style of pump head, the rotating piston moves to and from inside a cylinder; sucking in
fluid at the inlet while transferring and releasing the fluid at the outlet. Flow rates for piston pumps
are varied by changing either the motor speed or the stroke length. The FMI pump heads are excellent
for
precise fluid dispensing in non-sterile applications.
Note: Piston heads should not be used for pumping biological fluids or liquids containing
biological cells or cellular components. Piston heads generate high local shear forces
produce strong mechanical agitation, which may destroy cells and fragment large molecular
and
weight components, such as DNA or large protein molecules.
The LabTec™ FM-200 comes with a 600 RPM optically encoded, servo-controlled motor and a
FMI piston pump head.
Materials of Construction: Pump head fi s are either made out of Kynar or Tefzel. Pump piston
body are made out of ceramic. Exception: RHOO pump head model has stainless steel (1/8”ID)
and
piston. “LF” designation refers to a “Low Flow / Low Dead Volume” pump connection, utilizing
¼ - 28 HPLC fi s. All FMI piston pump heads have a maximum pressure rating of 100 psi (6.89

6.2 FMI Pump Heads: Installation
The following are directions to mount a FMI pump head on a LabTec™ controller. If you purchased
the LabTec™ controller with a FMI pump head already mounted, you can disregard these
directions. However, if you purchased your FMI pump head separately, you will need to mount the
pump head. The same instructions should also be used when dismounting an old pump head,
which you may want to replace with a new one:
1. Disconnect the power cable from the LabTec™.
2. Remove the two screws (6-32 x ½¨) from the underside of the LabTec™. These hold the motor
mounting plate in place.
3. Remove the four (6-32 x 3/8¨) Philip screws from the faceplate at the front of the LabTec™.
4. Carefully remove the pump / motor subassembly from the LabTec® controller. Disconnect
the motor cable (cable connecting the motor to the electronic board) before completely
removing the pump / motor assembly from the LabTec™ controller.
5. Mate the FMI pump head shaft to the flexible pump motor coupling. Fasten the shaft to the
coupling (the set screw on the coupling requires a 3/32 hex bit).
6. Fasten the FMI pump head with two screws (8-32 x ½”) to the back of the faceplate
(use an offset screwdriver).
7. Reconnect the pump motor cable and carefully place the pump / motor assembly back into
the LabTec™ controller.
8. Fasten the faceplate of the pump / motor assembly to the chassis with the four screws
removed in Step 3.
9. Fasten the motor mounting plate to the underside of the LabTec™ with the two screws
removed in Step 2.
10. Test the LabTec™ with the FMI pump head in place. Make fluid connections to the pump head.
Do not let the pump head run dry without fl id for any prolonged period of time.
6.3 FMI Pump Heads: Stroke Volume Adjustment
The knurled adjustment ring (black decal with markings, not the small knurled knob) on the FMI
pump head controls the stroke length and thus controls the output per motor revolution.
The adjustment ring is factory set at “200,” however, by turning the Adjustment Ring clockwise;
the stroke length and the pump output are reduced. However, do not turn the Adjustment Ring
below “50”. When turning the adjustment ring counter clock-wise from “50” to “450”, the
maximum stroke length / volume is obtained. Do not turn the adjustment ring above the
“450” setting.
The maximum stroke volume for the RHOO pump head is 25 μl, for the RHO pump head the stroke
volume is 50 μl while the RH1 pump head has a maximum stroke vole of 100 μl.
36
Page 37
6.4 FMI Pump Hea ds : Clean in g
Cleaning of Pump Head: Routine flushing with solvent before shutdown will work for most
applications. Set the LabTec™ for maximum pump speed, let the pump run until solvent appears
clear at discharge port. This should be for a minimum of 2 minutes. Do not leave process material
in the pump head overnight. Preventive maintenance is very valuable and ensures a long
operational pump life.
Important: Ceramic piston / cylinder sets are sensitive to neglect and may “freeze”
to dry out without adequate cleansing. Fill a loop of
fle
xible tubing with
flu
id that
neutralize the last fluid pumped. Then connect one end of the tube to the pump suction port, the
other to the discharge port. With the loop positioned above the pump head, the ceramic surfaces
will
if
allowed
thin or
and seal areas stay moist and mobile for extended idle periods.
However, if a piston freezes in the cylinder,
pump head from the base assembly so the whole pump head can be soaked in a suitable solvent.
If the head is not conveniently removable, the tube loop discussed in the previous paragraph may
Do Not Force It Free! Be gentle.
Try to remove the
permit solvent to dissolve the “frozen” residue in reasonable time.
6.6 FMI Pump Heads: Chemical Compatibility
FMI pump heads are well known for their robustness and overall chemical compatibility with
many process fl ids. The materials used in manufacturing FMI pump heads ar e inert to mos t
chemicals, however, the following exceptions must be observed:
When pumping: Toluene, Methylethylketone, Acetone, Ethanol, Hexyl Alcohol, Isobutyl Alcohol or
Isopropyl Alcohol, FMI pump heads with Tefzel (ETFE) housings must be used: RH1-CTC;
RHO-CTC; RHOO-CTC. The “T” in CTC designates Tefzel housing.
Tefzel has also excellent chemical resistance to most acids, bases or solvents.
Tefzel pump heads can be used in pump applications not exceeding 90°F and 100 psi (0 - 6.89
bar).
For pump applications involving fl ids above 90°F, FMI pump heads with Kynar (PVDF) housings
must be used: RH1-CKC, RHO-CKC, or RHOO-CKC, the “K” in CKC stands for Kynar.
Kynar has good chemical resistance to most fluids; however, Kynar pump heads must not be used
with Acetone, Ketones or Esters.
6.7 FMI Pump Heads: Viscosity Effects
The LabTec™ FM-200 is capable of pumping high viscosity fl ids. When pumping high viscosity
liquids, you should always use large bore tubing (1/ ” OD), slow pump rates and large stroke
volumes (set knurled Adjustment Ring to “400”) in order to avoid pump cavitations.
4
The LabTec™ FM-200 together with either a RHO or RH1 pump head can handle fluid viscosities
up to 2000 cps, and fluid viscosities up to 5000 cps when the fl id reservoir and feed line
connected to the pump inlet port are pressurized.

7.0 Pressure Sensor Installation
The SciLog® SciPres® pressure sensors are connected
in-line with the tubing and used in a flow through manner.
The SciPres® sensors have polysulfone and silicone
wetted surfaces.
The SciPres® sensors are available in 5 different sizes.

Part B: LabTec™ Software
1.0 Software Overview: Main Menu
The main menu of the LabTec™ consists of five (5) operational modes as shown on the next page.
By using the “Up” and “Down” keys, one can readily scroll through the main menu. Press the “Select”
key to enter a chosen operational mode, i.e. WGT RATIO (Weight Ratio). By pressing the “Select” key
the first level submenu is entered, which provides access to the “Exec” and “Edit” functions. In the
“Edit” submenu, the parameters for the dispensing application are selected. The LabTec™ has three
(3) dispensing modes, namely, Weight Ratio Dispensing, Volume Dispensing and Weight Dispensing.
WGT RATIO: In the Weight Ratio Dispensing mode, the LabTec™ is connected to an electronic,
top-loading scale and allows automatic sample weighing and dilution: The LabTec™ will tare the
scale after the sample container has been placed onto the scale. The sample to be diluted is then
placed into the container and the sample weight is captured and displayed by the LabTec™. The
diluent is automatically dispensed by the LabTec™ based on the user-defined sample to diluent
weight ratio. Monitoring and Alarm of backpressure is available in this mode.
VOLUME: In the Volume Dispensing mode, the LabTec™ dispenses user-defined volumes. In this
operational mode, the LabTec™ utilizes factory installed master calibration curves. These
calibrations are valid for a given pump head, motor and pump tubing combination. Typically the
calibration is carried at or near 100% motor speed although a lower pump speed setting may be
advisable for smaller volumes. A Re-Cal feature, available from the front panel, is used to fine-tune
this calibration, and to compensate for pump output changes due to peristaltic pump tube wear. Both
the Slow Factor and the Sniffle functions are available in the Volumetric Dispensing mode, as well as
Monitoring and Alarm of backpressure.
WEIGHT: In the Weight Dispensing mode, the LabTec™ is connected to an electronic, top-loading
scale while dispensing solutions by weight. In this operational mode, the LabTec™ does not require
calibration since dispensing by weight involves an already calibrated scale. Typically, dispensing by
weight is somewhat slower than dispensing by volume. The main reason for this slow-down lies with
the limited response speed of electronic scales. Both the Slow Factor and the Sniffle functions are
available in the Weight Dispensing mode, as well as Monitoring and Alarm of backpressure.
MANUAL: Allows manual pump speed control.
Note: Monitoring and Alarm of backpressure is available in this mode, but no data output is
available.
SETUP: This operational mode allows selection of various user preferences and interface options.

2.0 Weight Ratio: Weight Ratio Dispensing; Edit
SUMMARY: In the Weight Ratio Dispensing mode, the LabTec™ provides automated sample
weighing and sample dilution. With this operational mode, the LabTec™ must be connected to
an electronic, top-loading scale. The SETUP: Scale sub mode provides electronic scale options,
i.e. scales that can be interfaced with the LabTec™: Mettler, Ohaus, and Sartorius. The selected
scale is connected to Port S1. The LabTec™ also has provisions for printing / documenting your
dispensing data. The printer (P/N: 080-095) is connected to the LabTec™ via the Printer Port. Use
SETUP: Printer for setting up the printer communications parameters. Back pressure of any filter
in the system can be monitored by use of a SciPres® Pressure Sensor, enabling the pressure alarm
in SETUP: Press Sensor, and setting a user-defined limit.
When executing the Weight Ratio Dispensing mode, the LabTec™ will display “SCALE
INITIALIZATION / Please Wait”. While this message is being displayed, the LabTec™ checks the
scale communication. If scale communication fails the LabTec™ will display “SCALE ERROR /
Press any key”. Check the RS-232 cable connection as well as the communications parameters
in the scale. Also make sure the correct scale manufacturer is s e l e c t e d i n t h e S E T U P : S c a l e
submenu.
WGT FACTOR: Defines the weight ratio (multiplier) that is applied to the actual sample weight, as
determined by the scale, to arrive at the required diluent weight. For example, if the WGT FACTOR
is set at 9.00 (default value), and the actual sample weight is 10.0 grams, then the diluent target
weight is 90.0 grams resulting in a 10-fold sample dilution by weight.
SNIFFLE: The SNIFFLE function consists of a brief pump reversal to suck in the droplet that
typically hangs at the end of the dispensing tip. The length of time for the pump reversal is
user-selectable from 0 to 2.0 seconds. The SNIFFLE function is implemented at the end of
each dispensing cycle thereby avoiding carry-over between cycles and a cleaner dispensing
environment.
SLOW FACTOR: Defines the diluent weight that is dispensed slowly at the end of the dispensing
cycle. For example, if the diluent weight is 90.0 grams, then the SLOW FACTOR is selected to be
25.0 gm. When the LabTec™ initiates diluent dispensing, the first 65 gm. will be dispensed at a high
pump rate (e.g. 80% of max.), while the last 25 gm will be dispensed in a multiple step ramp down
of flow to avoid overshooting the diluent target weight. The SLOW FACTOR as well as the LabTec™
pump rate is user-selectable.
PUMP DIRECTION: Defines the rotation of the pump head; this parameter can be changed from
clock-wise (CW, default) to counter clock-wise (CCW).
PUMP RATE: Defines the relative pump speed (0% to 100% of max.) with which the diluent is being
dispensed. Typically, this parameter is set at 80% (default), however, a slower pump speed setting is
advisable if excessive back-splashing should occur.
TIME DELAY: Not used in the Weight Ratio mode, should be set to 1.0 (default).
COUNT: Not used in the Weight Ratio Dispensing mode, should be set to 1 (default).
CONTAINER WEIGHT: Enter the weight of a standard container or bag, and it will automatically be
deducted from the total weight of container and sample to arrive at the sample weight. The pump
will then proceed to dispense the calculated diluent weight, skipping the “Press RUN When Sample
is in Vessel” step and the initial tare of the scale.

Volume: Dispensing By Volume, Edit
SUMMARY: In the Volume Dispensing mode, the LabTec™ output must be optimized for a particular
pump head / motor / tubing combination. Once optimized and calibrated, the LabTec™ dispenses
user-programmable batch volumes with dependable precision and accuracy.
Note: If you requested pre-configured aliquots from Parker, then the LabTec™ was
delivered to you optimized, calibrated and ready for use.
A simple Re-Cal feature is available on the front panel to fine-tune the calibration, and compensate
for output changes due to peristaltic tube wear. In general, the LabTec™ should be re-calibrated
(Re-Cal key) at least daily, for very high accuracy dispensing applications a more frequent
re-calibration schedule is advisable.
For volumetric batch dispensing, the typical precision and accuracy ranges from 0.5% to 1.0%
depending on the dispensing rate. In general, the higher the dispensing (pump) rate, the poorer
the dispensing precision and accuracy.
Volume units are milliliters by default. To change to liters or m ic ro li te rs (μ l) , ac ces s S e tu p , P u mp ;
Volume Units.
DISP. VOLUME: Defines the volume to be dispensed in terms of milliliters. For example, to
dispense 50.00 mL, use the “Incr”, key to scroll to 50.00, then press “Select”. Default = 10.00.
TUBING: Defines the tubing used in the Head. Accesses appropriate factory calibration curve.
Choose between 13, 14, 16, 25, 17, & 18 for thin-walled in a 1081, and 15, 24, & 35 thick walled
when using a 1082.(This option not displayed if RH series head or Mag gear head is chosen) Default = 13.
CLEAR CV: This clears the Cumulative Volume (CV) value without having to cycle the system power,
which also clears this value. Press Yes, No, or Exit.
SNIFFLE: The SNIFFLE function consists of a brief pump reversal to suck back the droplet that
typically hangs at the dispensing tip. The amount reversal is user-selectable from 0 to 2.0
revolutions. The SNIFFLE default value is set at 0.3. The SNIFFLE function allows you to avoid carry-over between dispensing cycles and provides for a cleaner dispensing environment.
Default = 0.3 sec.
SLOW FACTOR: Defines the solution volume that is dispensed slowly at the end of the dispensing
cycle. For example, if the solution volume to be dispensed is 100 mL, then the SLOW FACTOR is
selected to be approximately 10% or 10 mL. When the LabTec™ initiates volumetric dispensing, the
first 90 mL (90% of total) will be dispensed at a high pump rate (e.g.100% of max.), while the last 10
mL (10% of total) will be dispensed slowly to avoid overshooting the solution target volume.
Default = 1.00 mL.
PUMP DIRECTION: Defines the rotation of the pump head; this parameter can be changed from
clock-wise (CW, default) to counter clock-wise (CCW). Default = CW.
PUMP RATE: Defines the relative pump speed (0% to 100% of max.) with which the batch volume is
being dispensed. Typically, this parameter is set at 100% (default), however, a slower pump speed is
advisable if excessive back-splashing occurs. Default = 100%.
TIME DELAY: Defines the time interval between dispensing cycles (0.1 to 60 seconds).
Default Setting: 1.0 sec.
COUNT: Defines the number of repeats of the dispense that occur. For example, when COUNT=10,
then the selected DISP. VOLUME will dispense10 times. Default Setting = 1.

Volume Dispense Mode: Calibration
The LabTec™ has two volumetric calibration features, built in Factory Calibrations as well as
a Re-Cal feature.
The LabTec™ utilizes a number of factory calibrations. The LabTec™ accesses built in calibration
curves based upon the motor rpm setting in SETUP: Pump: Motor RPM, the head setting in SETUP:
Pump: Pump Head and the Tubing setting. When using a peristaltic head, select the correct tubing
and you’re ready to optimize and finally perform a RE-CAL (see below).
Calibrations for RH series heads are based on a vernier setting of 200, and those for the Magnetic
gear heads are specific to that head. Again, a simple optimization and RE-CAL, and you’re done. If you
have not requested Parker to pre-configure and optimize the dispensing aliquots for you, or are
editing a new one, you need to confirm the aforementioned settings.
Optimization involves choosing and fine-tuning the Pump Speed and Slow Factor settings to obtain
fast, precise aliquots without overshooting. Small aliquots require slower pump speeds than large
ones, and a similar relationship with aliquot size, pump speed and Slow Factor exists. Faster pump
speeds will require larger Slow Factors. Please refer to Part C of this manual for example dispensing
parameters that will provide a good starting point.
The Re-Cal feature allows you to quickly update the Factory Calibration. For peristaltic pumps in particular, slow pump tube wear will change the pump output over time. The Re-Cal function will compensate for this change in pump output by
adjusting the stored calibration curve.
For re-calibration purposes, you should dispense at least three (3) aliquots (distilled water) of your
selected volume; e.g. 150.00 mL. Record the weight of each aliquot, and then determine the average
(AV) aliquot weight. Use an electronic top-loading scale to weigh each aliquot.
For example, assume that you obtained the following values:
Trial 1 152.50 g
Trial 2 151.80 g
Trial 3 152.10 g
AV = Average Value: 152.13 g
In this example, you would adjust (assume 1.00 mL = 1.00 grams) the AV parameter to 152.13; the
LabTec™ will automatically correct the factory calibration curve.
The Re-Cal feature is accessible through the Re-Cal key on the LabTec™ front panel. As shown on the
opposite page, the Re-Cal feature is active when the following is displayed.
DISPENSING

Only the AV parameter (AV= Average Value) can be changed in this display, use the “Incr.” and “Decr.”
keys to adjust the AV parameter to match the amount collected. You may want to repeat the Re-Cal in
order to check the improved dispensing accuracy.

Part C: LabTec™ Dispensing Applications
1.0 Weight Ratio Dispensing: General Information
The Weight Ratio Dispensing mode is designed for automated weighing and diluting of samples.
In this operational mode, the LabTec™ is connected to an electronic, top-loading scale.
The LabTec™ will tare the scale after the sample container has been placed onto the scale.
The sample is then placed into the container and the sample weight is stored and displayed by
the LabTec™. The diluent is automatically dispensed by the LabTec™ based on a user-defined
sample to diluent weight ratio. For example, if the sample weight happens to be 10.00 grams and
the user-selected weight ratio is 9.00, then the LabTec™ will dispense 90.00 grams of diluent to
provide 10-fold dilution by weight. Regardless of the sample weight, the desired dilution ratio will
be maintained. Only an approximate sample weight needs to be placed into the sample container.
1.1 Sterile Dispensing:
When sterile liquids need to be dispensed, two (2) pump dispensing options are available:
First, the LabTec™ CP-200 mounted with the 1082 peristaltic pump head is the
method of choice when dispensing pre-sterilized solutions. Utilizing
Silicone pump tubing and 0.2 μm filter cartridge, sterility of the liquid can be
autoclavable
readily
maintained during the dispensing process. The sterilized solution comes only in
contact with the sterilized #24 Silicone pump tubing.
Second, the LabTec™ MP320 mounted with a Magnetic Gear Pump Head (Model 201) and used
together with a 0.2 μm filter cartridge, allows in-line filter sterilization of
dispensing. This method avoids the need for pre-sterilizing, i.e. autoclaving of
significant savings both in labor and energy. Here the magnetic gear pump head is
solutions while
solutions; a
recommended because of the high output capacity (3.5 liters per minute).
In-line filter sterilization is recommended when large batch volumes of sterile solutions are
needed, e.g. dilution of combined samples in Salmonella bacteriological testing which typically
require 2-4 liters of sterile diluent per sample. By using a SciLog® SciPres® Pressure Sensor,
you can monitor the backpressure generated as the filter becomes plugged, and set a user
definable limit to either Alarm Only (audible beep) or Pump Stop (stops pump and beeps).
In-line filter sterilization is also recommended for large volume dispensing applications in
media kitchens. Utilizing large surface area filtration devices, i.e Parker PROPOR SG
DEMICAP P/N: ZESGB-020-HH-PS3, 1500 to 2000 liters of media can be dispensed
filter cartridge. However, the actual filtration capacity is heavily dependent on the
load of the solution to be filtered. Your Parker Territory Manager
can help identify the filter
with a single
particulate
suited for your application.
When using the LabTec™ with a 201 magnet gear pump head, you need to install an in-line
check valve (P/N: 400-530) preferably at the pump discharge side.

1.2 Scale Installation:
In the Weight Ratio Dispensing mode, the LabTec™ must be connected to a top loading electronic
scale. The scale parameters which are relevant to the particular scale must be entered and stored
in the scale’s memory. Carefully check that all required parameters have been entered and
accepted by the scale.
In the LabTec™ Setup: Scale submenu, select the scale manufacturer; the LabTec™ will
automatically implement the correct communications parameters. Connect the appropriate Scale
to LabTec™ cable to the “Scale” port of the LabTec™, as well as to the serial port of the scale. To
test the serial communication between LabTec® and scale, enter the Weight Ratio mode and
select the “EXEC 1”display, then press “Select”:

2.0 Weight Ratio Dispensing: How to Get Started
If a data printout is desired, connect the cable (P/N: 080-096) between the LabTec™ “Printer” port
and the Parker printer (P/N; 080-095). In the LabTec™ Setup: Printer submenu, make sure all the
printer communications parameters have been entered. Turn on the printer, in the
the Weight Ratio mode, then press “Exec” key; the fi st line to be printed will consist
LabTec™ select
of weight ratio
dispensing parameters.
Install the pump tubing: For most weight ratio dispensing applications, #24 thick-walled silicone
pump tubing is recommended (requires a 1082 peristaltic pump). Use approximately six (6) feet of
#24 tubing; install the tubing such that two feet of tubing is located on the discharge side while four
feet of tubing are located on the suction side of
the . (These lengths are guidelines only.)
Note: This arrangement allows used pump tube sections located in the to be replaced with new
tube section located at the suction side of the pump. When advancing pump tubing in this manner, the used pump tube sections end up on the pump discharge side.
If you use a 201 Magnetic Gear Pump Head, #24 Silicone pump tubing is also recommended. However
in this case, pipe adapters (¼ x 1/8”, male, P/N: 400-500) are installed at the inlet and outlet ports of
the 201 magnetic gear pump head. The #24 Silicone tubing slips tightly over the inlet and outlet pipe
adapters.
The scale should be located next to the LabTec™. On the discharge side, fasten the pump tubing to
a ring stand (P/N: 400-420) using nylon ties. The dispensing tip should be secured with a clamp and
located above the scale with sufficient clearing to allow the easy removal of any sample bags or
containers. On the suction side of the LabTec™, secure the pump tubing to the solution reservoir.
Press the “Prime” key at the LabTec™ front panel until all of the tubing is filled with solution.
Consult the Weight Ratio Edit section of the manual to edit the weight ratio dispensing parameters.
Press “Exec” key, select “Exec 1”, the LabTec™ will show the following display:

Remove your filled sample bag or container and initiate the second dispensing cycle.
Note: If you have more than one WGT FACTOR, store one WGT FACTOR in “Edit 1”, e.g. “9.00”,
while a second WGT FACTOR is stored in “Edit 2”, e.g. “99.00”. Up to ten different sets of
parameters can be stored in “Edit 1” through “Edit 10”.
The following information should be used as a general guide in selecting optimal dispensing
parameters: This data was collected with a 600 RPM LabTec™ Dispenser mounted with a 1082 pump
head; the “Tube Size” parameter refers to thick walled silicone pump tubing size #24.
The “Slow Factor” is implemented at the end of each dispensing cycle to allow the electronic scale to
stabilize. Thus a Slow Factor of 20.00 mL indicates that the last 20 mL will be dispensed at reduced
pump speed.
Note: The LabTec™ will stop pumping just prior to reaching the target weight; once the scale has
stabilized, the LabTec™ will complete the dispensing cycle.
The end of the dispensing cycle will be indicated by a “beep” followed by the display “Dispensing
Completed”. The “Sniffle”, i. e. momentary pump reversal at the end of the dispensing cycle, is set at
its default value of 0.3.

Magnetic Gear Pump:
The following information should be used as a general guide in selecting optimal dispensing
parameters. This data was collected with a 3400-RPM LabTec™ Dispenser mounted with a
201 Micropump Head. A check valve (P/N: 400-530) was used as a dispensing spout.
The “Slow Factor” is implemented at the end of each dispensing cycle to allow the electronic scale
to stabilize. Thus a Slow Factor of 25 mL indicates that the last 25 mL will be dispensed at reduced
pump speed.
Note: The LabTec™ will stop pumping just prior to reaching the target weight; once the scale has
stabilized, the LabTec™ will complete the dispensing cycle.
The end of the dispensing cycle will be indicated by a “beep” followed by the display
“Dispensing Completed”. The “Sniffle” function is turned off i.e. Sniffle = 0.0
Edit Parameters: All dispensing was done with a 201 Micropump Head.

3.0 Dispensing By Volume: General Considerations:
3.1 Dispensing of Pre-sterilized Solutions:
1. For volumetric batch dispensing of pre-sterilized, i.e. autoclaved solutions, the 1082
peristaltic pump head is recommended together with thick walled (#24 or #15) Silicone
pump tubing.
2. For volumetric batch dispensing in the 2.5 mL to 10 mL range, use #15 Silicone pump tubing (
P/N: 400-115).
3. For volumetric batch dispensing in the 10 mL to 500 mL range, use # 24 Silicone pump tubing
(P/N 400-124).
4. Both #15 and #24 Silicone pump tubing can be autoclaved repeatedly.
3.2 Dispensing with In-Line Filter Sterilization:
•
For volumetric batch dispensing with in-line filter sterilization, the 1082 peristaltic pump head
is recommended together with thick-walled (#15 or #24) Silicone pump tubing.
•
For volumetric batch dispensing in the 10 mL to 500 mL range, use # 24 Silicone pump tubing
(P/N: 400-124). The large-capacity Parker PROPOR SG DEMICAP
P/N: ZESGB-020-HH-PS3 is recommended.
•
For large-volume batch dispensing with in-line filter sterilization in the multi-liter range, use
the 201 Micropump Head. The large-capacity PROPOR SG DEMICAP P/N: ZESGB-020-HH-PS3
is recommended.
•
Your local Parker representative can help you determine the correct filter for your application.
3.3 Dispensing of Non-Sterile Solutions:
Either the 1082 or the 201 Micopump Head can be used. For batch volumes up to 500 mL,
the 1082 pump head is recommended. For larger batch volumes, the 201 Micropump
Head provides a faster dispensing capability. However, the 201 Micropump Head is not
recommended for solutions containing particulates or shear sensitive solutions.
Note: If you requested a custom calibration from Parker, then the LabTec™ was delivered to you
calibrated and is ready for use.

4.0 Dispensing by Volume: How to get started
Select your pump tubing; use #24 or #15 Silicone tubing if you have a 1082 peristaltic pump head.
Selec t # 24 tub in g i f you in te nd to disp en se al iq uots la rg er th an 10 mL, use #15 pump tubing if you
intend to dispense aliquots smaller than 10 mL.
Consult, Volume Dispense Mode: Edit, go to the following display:
After having connected the tubing to the solution reservoir, fill the tubing with solution and expel all
air from the tubing by pressing the “PRIME” key at the LabTec™ front panel. You are now ready to
setup your dispense using the built-in calibration; go to the following display and press “Edit” key.
Select the following parameters for “Edit 1”:
“DISP VOLUME”
“TUBING”
“SNIFFLE” enter “0.3”
“SLOW FACTOR”
“PUMP RATE”
“TIME DELAY”
“COUNT”
enter “50.00 mL”
choose “24”
enter “2.5 mL”
enter “80%”
enter “0.1 sec”
enter “1”
First press “Exit”, then press “Exec” (key “A”), and then “Select” for Exec 1. The following display
will appear:
VOLUME SET:
Press RUN When Ready
Edit Prime
50:00 mL
When you press the “RUN” key, the LabTec™ will dispense one (1) 50.00 mL aliquot.
At this point you may want to check the accuracy of the LabTec™. For this purpose use an electronic
scale with 0.01-gram readability, e.g. Mettler PG5002-S or equivalent. Dispense at least three
50.00 mL aliquots of distilled water, record the weight of each aliquot, and then determine the average aliquot weight. For example, assume that you obtained the following results:
Trial 1 50.80g
Trial 2 50.50g
Trial 3 51.10g
AV = Average Value: 50.80g
After you have dispensed the third aliquot, press the RE-CAL key, the LabTec™ will show the following
display:
DV: 50.00
AV: 50.00
Incr. Decr. Select
Use the “Incr.” And “Decr.” Keys until AV = 50.80, the average aliquot size, then press “Select”. The
Calibration has now been corrected and will compensate for the inaccuracy.
The following information should be used as a general guide in selecting optimal dispensing
parameters: This data was collected with a 600 RPM LabTec™ Dispenser mounted with a
1082 pump head; the “Tube Size” parameter refers to thick walled silicone pump tubing sizes: 15 and
24.
The “Slow Factor” is implemented at the end of each dispensing cycle to avoid overshooting of the
target volume. Thus a Slow Factor of 1.00 mL indicates that the last 1.0 mL will be dispensed at
reduced pump speed. Typically, for dispensed volumes less than 50 mL, the “Slow Factor” is
approximately 5% of the selected Dispensed Volume. The “Sniffle, i. e. momentary pump reversal
at the end of the dispensing cycle, is set at its default value of 0.3.
Note: After changing pumping parameters, i.e. changing pump tubing, Pump Speed, Slow Factor
or Sniffle settings, you should re-calibrate the LabTec™ Dispenser (see Re-Cal feature) in order to
maintain a high accuracy / precision level.

Dispensing By Weight: How to Get Started
If a data printout is desired, connect the cable (P/N: 080-096) between the LabTec™ “Printer” port
and the Parker printer (P/N; 080-095). In the LabTec® Setup: Printer submenu, make sure all the
printer communications parameters have been entered. Turn on the printer, in the
the Weight mode, then press “Exec” key; the first line to be printed will consist of
LabTec™ select
weight dispensing
parameters.
Install the pump tubing: For most weight dispensing applications, #24 thick-walled silicone pump
tubing is recommended (requires a 1082 peristaltic pump). Use approximately six (6) feet of #24 tubing; install the tubing such that two (2) feet of tubing are located on the discharge side while four (4)
feet of tubing are located on the suction side of the .
(The lengths here are only guidelines.)
Note: This arrangement allows used pump tube sections located in the to be replaced with new
tube section located at the suction side of the pump. When advancing pump tubing in this manner, the used pump tube sections end up on the pump discharge side.
If you use a 201 Magnetic Gear Pump Head, #24 Silicone pump tubing is also recommended. However
in this case, pipe adapters (¼ x 1/ ¨, male, P/N: 400-500) are installed at the inlet and outlet ports of
the 201 magnetic gear pump head. The #24 silicone tubing slips tightly over the inlet and outlet pipe
8
adapters.
The scale should be located next to the LabTec™. On the discharge side, fasten the pump tubing to
a ring stand (P/N: 400-420) using nylon ties. The dispensing tip should be secured with a clamp and
located above the scale with sufficient clearing to allow the easy removal of any sample bags or
containers. On the suction side of the LabTec™, secure the pump tubing to the solution reservoir.
Press the “Prime” key at the LabTec™ front panel until all of the tubing is filled with solution.
Consult Weight Dispensing Mode: Edit for editing your weight dispensing parameters.
DISP. WEIGHT: Defines the dispensed weight in terms of grams. For example, to dispense 25.00
grams, use the “Incr,” key to scroll to 25.00, then press “Select”.
SNIFFLE: The sniffle function consists of a brief pump reversal at the end of the dispensing cycle to
suck in the droplet that typically hangs at the end of the dispensing tip. Select SNIFFLE = 0.0.
SLOW FACTOR: Defines the diluent weight that is dispensed slowly at the end of the dispensing cycle.
For example, if the diluent weight is expected to be 100 grams, then the SLOW FACTOR is selected to
be approximately 25% or 25.00 grams.
PUMP DIRECTION: Defines the rotation of the pump head, this parameter can be changed from
clock-wise (CW) to counter clock-wise (CCW).
PUMP RATE: Defines the relative pup speed (0% to 100%) with which the diluent is being dispensed.
S e l e c t P U M P R A T E = 8 0 % .
TIME DELAY: Defines the time interval, in seconds, between dispensing cycles.
COUNT: Defines how often the dispensing cycle will be repeated. For example, when COUNT = 10,
then the selected DISP. WEIGHT will be dispensed 10 times.

6.0 Care and Use of Sterilizing Filters
Many laboratories use sterilizing filters instead of autoclaving to sterilize media. Using filters instead
of autoclaving increases productivity in the laboratory and protects technicians from handling hot and
/ or heavy containers. Autoclaving is very labor intensive and also uses a great deal of energy.
When using filters, as with any technology, there is a protocol you should develop and always should
be followed to safely and effectively implement your application. The following are guidelines you
should consider making part of your sterilizing protocol.
Procedure for Filtering:
1. To “Prime” a filter means to push all the air out that is in the new un-used filter and to fill the
filter with the solution that needs to be filtered. You want to pr ime a fi lt er slowly to avoid c re at in g
“air pockets” within the filter.
2. Be sure to open the vent on your filter before you prime it.
3. You will connect the filter to your LabTec™ tubing. Set the pump rate at a low value, such as 25%
of maximum speed when you are priming the filter.
4. Press “RUN” on the LabTec™ while you are in the Manual Mode.
5. Periodically Tap the filter as it is being primed; this will dislodge any bubbles and send them on
their way.
6. If you pump too quickly while you are priming the filter, air bubbles may remain trapped in the
filter. These air bubbles will continually come out during dispensing and affect the precision of
your volumetric dispenses. The air bubbles will not affect your weight-ratio or
gravimetric dispenses.
7. Flush the filter with the vent open until solution comes out of the vent. This means the filter is
completely full of liquid, and the priming process is complete.
Autoclaving the Filter:
1. The sterilizing filters you have received are sterile as long as the packaging is unopened.
Make sure you do not open the filter package until you are ready to use.
2. Repeated autoclaving may distort different parts of the filter. Distortion will result in rupturing the
filter. Thus, you should autoclave the filter only once.
3. Autoclave for at least 20 min. Typical maximum autoclave temperature is 134 °C at 2 bar.
Pumping Heated Solutions through the Filter:
1. If the solution to be pumped is hot, make sure you heat the solution gradually.
2. Maintain a constant temperature.
3. Maximum temperature for prolonged pumping through your filter is 180 °F.
8
Page 83
Troubleshooting the Filters:
1. Your filter should be changed on a regular basis. Try to choose a filter size that will
accommodate the total volume you need filtered in a day, the flow rate you need through
the filter.
2. Sterilizing filters have a pore size of 0.22 microns. If you have a very “dirty” solution, you may
want to send your solution through a series of filters, such as first through a pore size of
5 microns to catch the very big, chunky particulate matter and then through the 0.22 micron
filter to sterilize
3. Be sure that you have dissolved your media before beginning to filter.
4. You may want to heat the media a little to ensure and speed the dissolving.
5. Be sure to slow the pump down during the priming of the filter.
6. If you are filtering a broth when the solution is hot, allow the temperature to decrease a
little before you filter.
7. Go to the next larger size filter if you need to higher capacity or need to use a much faster
pump speed.
Reusing Sterilizing Filters:
1. Chose a filter size that will accommodate the total volume you typically need in a day. For best
results use the proper sized filter for your job size.
2. If you have a large sterilizing cartridge filter and you have “used” only a fraction of its life, you
can carefully remove it from its tubing connections and wrap it in plastic wrap and place in your
refrigerator. There it must be kept at 4 °C. It can be stored in this manner for several days.
When you want to reuse the filter, carefully reattach tubing connections and use.
3. If you have a “used” filter and would like to reuse it, it is possible to back flush the filter with
sterile water, autoclave and then reuse. This procedure should not be repeated more than once,
since there is the possibility of repeated autoclaving separating the filter housing from the filter
layers. This procedure is not recommended, but is possible.
4. For best results use the proper sized filter for your job size. Consider the costs of a sterilizing
filter as a consumable, which is less expensive than autoclaving.
5. “Squeezing” too much life out of a filter will tend to produce unacceptable results.

Part D: Troubleshooting - Peristaltic Pump Heads
When this occurs:
When “Check Pump Head” error
occurs with your peristaltic head.
When peristaltic pump head turns,
but no fluid flows.
When the pump head turns ok with
no tubing installed, won’t turn when
you put tubing in, and you don’t get a
“Check Pump Head” error.
When “Scale Error” “Hit any key”
shows on your screen.
When the pump is acting behaving
strangely.
The aliquots are all wrong; it gets data
from the scale, but slows down
way too early; etc.
Check the following: Possible solution
1. Does “Check Pump Head” occur
with no tubing in the head?
2. Confirm the tubing sizes you are
using.
1. Check the tubing size and pump
head type, as you may be using the
wrong size for that head.
2. Tubing Size is ok
The coupler is loose or
broken.
1. Is your scale turned on, and are
the cables tight?
2. Ok, the scale is on, cables are ok,
and it still won’t work?
3.
Ok, the scale is chosen correctly,
and it still doesn’t work.
Now what?
1. Has someone else used your
LabTec™?
2.
Have you had electrical problems
in the building lately?
1. If it occurs with no tubing in the
head, call Parker.
a new motor.
2. If no, make sure you are using the
correct size tubing. Thick walled
tubing in a thin wall pump head will
cause this, and may break the head.
1.
1081 is for thin walled
tubing, and 1082 is for thick-walled
tubing. Thin-walled tubing in a thick
walled head won’t produce much
flow. Use the correct size tubing.
2. The pump head may be cracked from
being forced closed with the tubing
crosswise or the wrong size tubing.
Contact Parker for repair or
replacement parts.
Contact Parker for
support, or to arrange for
and an RGA#.
1.
Press any key to clear the error,
tighten the cables, turn on the
s c al e , an d t r y i t ag a i n .
2. Check Section 4, Setup: Scale of
this manual, then go to Setup
Mode of the pump, select Scale,
then Scale Mfr, and confirm the
selection is correct.
3.
Either refer to the same manual
section mentioned above to check
the scale settings, or call Parker
tech support for help correcting
them.
1. If someone other than yourself
or your supervisor has changed
the settings without your
knowledge, you can to return
them to their original settings.
2.
Power spikes and brown outs can
cause problems. Enter Setup;
Pump, and then select Factory
R es e t . T h is s te p is a la s t r e so rt .
This will return the unit to the
factory default values. You will
need to return to Setup; Pump;
Motor RPM, and verify its setting,
as well as Setup, Pump; Pump

also need to reenter your aliquots
and recalibrate them. Call Parker

Piston and Magnetic Gear Heads
When this occurs: Check the following: Possible solution
When “Check Pump Head” error occurs with your piston or magnetic gear
head.
When your piston pump head seems to
turn and the motor runs, but no fluid
flows.
When your magnetic pump head seems
to turn and the motor runs, but no fluid
flows.
When “Scale Error” “Hit any key”
shows on your screen.
When the pump is behaving strangely.
The aliquots are all wrong; it gets data
from the scale, but slows down way too
early; etc.
1. When was the last time you had the
head serviced?
2.
Are you pumping a gritty solution,
or one that can crystallize if allowed
t o d r y o ut ?
Either the piston is broken, or the
coupler is loose.
1. Has the unit run dry?
2. Is it a high viscosity fluid?
1. Is your scale turned on, and are the
cables tight?
2. Ok, the scale is on, the cables are ok,
and it still won’t work?
3.
Ok, the scale is chosen correctly, and
you still get no data?
1. Has someone else used with
your LabTec™?
2. Have you had electrical problems
in the building lateley?
1. If you believe the head is stuck due to
being dried out, you can try wetting
it by placing an appropriate solvent in
the upper tubing overnight.
2. If it still won’t turn, contact Parker
to arrange an RGA to send your
pump in for service, or
service kit if you have a
gear head.
Contact Parker for tech support or to
arrange for service
for your pump and
RGA#.
1. Magnetic gear head pumps do not
dry prime well after they have been
broken in. You must keep the pump
wet. Be sure you are using a check
valve as your dispensing tip so the
fluid doesn’t run back into the
container.
2. Magnetic gear heads do not perform
well with viscous fluids, as they can
decouple. Either reduce the viscosity,
provide head pressure, or choose a
different style of head.
1.
Press any key to clear the error,
tighten the cables, turn on the scale,
and try it again.
2. Check Section 4. Setup: Scale of this
manual, then go to Setup Mode of the
pump, select Scale, then Scale Mfr.
and confirm the selection is correct.
3.
Either refer to the same manual
section mentioned above to check
the settings on the scale itself, or
call Parker for technical support
help in correcting
them.
1. If someone other than yourself or
your supervisor has changed the
settings without your knowledge,
you can return them to their original
settings.
2. Power spiked and brown outs can
cause problems. Enter Setup; Pump,
and then select Factory Reset. This
step is a last resort. This will return
the unit to the factory default values.
You will need to return to Setup;
Pump; Motor RPM, and verify its
setting, as well as Setup, Pump;
Pump Head to verify it as well. You
will also need to re-enter all your
aliquots and re-calibrate them. Call
Parker domncik hunter for technical
purchasing a
magnetic
support if needed.

SciDoc Documentation Software
When this occurs:
When you get a “Device Error, Com Port
Not Available” error from your computer.
You have SciDoc open, and the LabTec™
running, but no data is being collected.
Check the following:
This is a computer related error, not
one generated by the pump. The Com
port you specified is in use or does not
exist on your computer.
There is no communication between
the spreadsheet and the LabTec™.
1.
Check that you are using the correct
cable, and that it’s installed correctly.
2.
WinWedge may not be running.
3.
WinWedge may not be able to access
the Com Port.
Possible solution
1.
Check Device Manager from the
properties page of the My Computer
Icon. Expand the + next to Ports, Com
and LPT. What Com ports exist, and
are they functioning properly?
2.
If all in Device Mgr is fine, then some
other program is using the Com Port,
consult your IT or MIS dept. for
assistance. You may have to specify
a different Com Port for use with the
SciDoc spreadsheet.
3.
Known devices/programs that cause
this error:
a.
Installed but not used Serial Mouse.
b.
RS-232 bar code reader installed on
the same Com port.
c.
Hot Sync or Synchronize program
for your PDA.
d.
An already open instance of SciDoc
using that Com port.
1.
The RS-232 cable for the PC can look
nearly identical to that used for the
scale. They should be labeled.
2.
Check the System Tray for the
WinWedge Icon. If it’s not there, click
on the Setup Button, and indicate
which port you are using.
3.
You will find a button on the Taskbar
indicating a “Device Error”, refer to
the previous troubleshooting subject
for help with Com Port errors.
