Section 5
Tubing Selection and Installation
5.1 T ubing Selection
The Model EP-1 Econo Pump may be used with most flexible tubing
having an inner diameter less than or equal to 3.2 mm (1/8"), and a wall
thickness of 1.0 mm or less, including silicone, Tygon, and PharMed.
Silicone tubing, the most inert of the three, is suitable for aqueous and polar
solutions. Tygon is suitable for most aqueous solutions. It will generally
have the shortest lifetime of the three. PharMed is the longest lasting of the
three, and will provide the most consistent flow rate over time. Table 5.1
shows approximate flow rate ranges with different tubing sizes. Flow rates
above 20 ml/min may be obtained by plumbing two channels of 3.2 mm
tubing through the pump and joining them at the output.
Table 5.1. Approximate Flow Rate Ranges
Tubing length and the amount of tubing prestretch have a significant
effect on both flow rate calibration and reproducibility of flow. The PharMed
tubing supplied with the Econo Pump has been cut to a predetermined length
to accommodate tubing prestretch. (Silicon tubing in precut lengths is also
available from Bio-Rad. See ordering information in appendix C.)

When using tubing other than precut tubing from Bio-Rad, the tubing
must be cut to the following lengths to accommodate prestretch:
Tubing Length
Tygon, PharMed 179 mm +/- 1.5 (7.04" +/- 0.05)
Silicone 171 mm +/- 1.5 (6.75" +/- 0.05)
Install tubing onto the pump head as described in Section 5.2.
Warning: If using tubing other than the type supplied by Bio-Rad, make
sure the wall thickness is not greater than 1.0 mm. Using tubing with a
greater wall thickness can damage the pump and void your warranty.
5.2 T ubing Installation
1. Referring to Figure 5.1, pull the platen cam lever away from the pump
head to unlock the platen and slide the platen away from the pump head
frame assembly, exposing the rollers.
Fig. 5.1.Tubing installation.
2. Slip a lock-ring onto one end of the tubing. See below for the size and
color of each lock-ring. Insert a barbed female luer-fitting into the same
end until the tubing reaches the flange of the fitting. Clamp the luer-fit-
ting into place by sliding the lock-ring along the tubing over the barbed
fitting (see Figure 5.2). Repeat on the other end of tubing.
Note: Use of lock-rings is required only when operating at pressures
above 10 psi.

Yellow 3.2 mm (1/8")
Fig. 5.2. Attachment of tubing fittings.
3. Insert one end of the tubing into the tubing retaining bracket of the
pump head. Lightly pull the tubing around the rollers to remove slack.
Attach the other end of tubing into the tubing retaining bracket on the
opposite side of the pump head.
4. Slide the platen back into the pump head frame assembly until it rests
up against the tubing. Press the cam lever in toward the pump head,
locking the platen up against the tubing and rollers. Note that the
platen can be inserted with the cam lever on the left or the right.
5.3 Platen Adjustment
Proper adjustment of the platen pressure increases flow stability,
minimizes flow pulsation, and prolongs the life of the tubing.
Once the tubing is installed in the pumphead, loosen the platen
adjustment screw, located on the front of the platen, counterclockwise until
the stop is reached. For one piece of either PharMed or Tygon tubing, the
platen is properly adjusted at three to four full turns clockwise from stop.
For one piece of silicon tubing, the platen is properly adjusted two full turns
clockwise from stop. When using two pieces of tubing, approximately 50%
more turns clockwise from stop will be required.
10
Note: Overtightening the platen adjustment screw will reduce flow rate
and shorten tubing life. If the platen is too loose, flow rate will decrease
as backpressure increases.
Section 6
Stand Alone Operation
The Model EP-1 Econo Pump functions as a stand-alone pump. By
specifying the pump tubing size, it allows you to enter a flow rate rather
than a nominal pump speed setting. (An uncalibrated Econo Pump will
display pump speed as percent of maximum rpm.) There are two ways to
calibrate the pump: through a preset tubing size or through a user
calibration procedure.
Flow Rate Calibration with Pre-Selected Tubing Sizes (0.8, 1.6,
and 3.2 mm ID)
1. With the pump in Stop mode, install tubing as described
in Section 5.2.
2. Press the key in the lower left-front of the pump panel
corresponding to the pump calibration feature, and
continue pressing until the indicator light corresponding
to either 0.8, 1.6, or 3.2 mm ID tubing is lit.
3. The LED display reads ml/min for any of these pre-programmed tubing settings. If improved flow rate accuracy
is desired, see User Calibration Procedure below.
4. The pump is now automatically calibrated for the specific
tubing size. Press the Run/Stop key to start flow. Increase
or decrease the pump speed with the Arrow keys.
User Calibration Procedure
1. Install tubing as described in Section 5.2. Connect
pump inlet to a container of water or buffer. Connect a
length of tubing to the pump outlet.
2. Run pump to purge air from tubing, then stop pump.
Place the end of the outlet tubing in an empty graduated
cylinder.

3. Press Calibration key until “CAL” is displayed. Press
the Run/Stop key. Pump will run for 5 minutes at 25%
of maximum speed, and the display will count down
time.
4. When pump stops, read the volume of fluid on the
graduated cylinder. Using the Arrow keys, enter this
amount on the display. Alternatively, when a suitable
volume of liquid has been collected, pressing Run/Stop
will turn off the timer and stop the pump. Enter volume
collected as described.
5. When the value on the display matches the volume
collected in the graduated cylinder, press Calibration.
The “CAL” indicator light will glow steadily, indicating
that the pump is calibrated. DO NOT select a tubing
size at this point, even if you are using one of the standard
sizes. The pump will “remember” the calibration key
even if it is switched off or disconnected from the
power line.
6. Set desired flow rate using arrow keys.
Note: Flow rate depends on condition of tubing, platen
adjustment, and back pressure. For maximum flow rate
accuracy it may be necessary to recalibrate as the tubing
ages, when the tubing is replaced, if the platen is readjusted, or if back pressure changes significantly.
Section 7
Operation with other Instruments
The Model EP-1 Econo Pump can be used with other chromatography
components (Model 2110 and Model 2128 fraction collectors), or with the
BioLogic System, the high resolution liquid chromatography system. Each
of these applications is discussed below.

7.1 Use of the Econo Pump with the Model 2110
Fraction Collector
The Econo Pump is capable of controlling the Model 2110 Fraction
Collector. The pump must be calibrated in order to run a fraction collector
program. See Section 6 for calibration instructions.
Use System Cable 1 (catalog number 731-8261) to connect the Econo
Pump to the fraction collector. Connect the 9-pin “D” connector to rear of
the Model 2110, and the mini-DIN plug to the rear port of the Econo Pump
with the collector icon. (See Figure 4.2.)
To program a simple time-based collection method, follow these
instructions.
1. Press the Fraction Collector key on the pump front panel
to enter the fraction collector Edit mode. Note that the
fraction size and ml indicator lights are flashing, prompting entry of fraction size. Enter the fraction size in 0.1 ml
increments using the Arrow keys. After fraction size is
selected, press the Fraction Collector key once more to
confirm the fraction size.
2. Enter a void volume (Vo) in 1 ml increments using the
Arrow keys. This feature allows the user to begin collecting fractions only after a pre-set volume of liquid
(i.e., the void volume) has passed through the column.
Press the Fraction Collector key to confirm this value. If
a void volume is not desired, enter 0.
Note: The optional Model SV-3 Diverter Valve (catalog
number 731-8235) is required to use the void volume
feature of the Model EP-1 Econo Pump.
3. Select the total run volume (Vt) in 1 ml increments
using the Arrow keys.* If zero is entered and confirmed,
the fraction collection scheme is disabled. To resume
data entry, see Step 1 above. All values previously
entered remain in the memory until other values are
entered to replace them.
* Note: The Econo Pump will automatically shut off upon
reaching the total run volume (Vt).

display shows the estimated number of fractions to be
collected.
5. Press the flashing Fraction Collection key once more to
enable the fraction collector. To actuate the fraction
collector, press the Program Run key after starting the
pump. (The fraction collector can be programmed with
the pump running or stopped.) After the fraction
collection program is initiated, the LED display shows
the progression of the fraction collection scheme in
minutes, to the nearest tenth of a minute.
6. While a program is running, the user can use the Arrow
keys to display the ml of output, the progression of the
collection in min, the flow rate in ml/min, or the percent
of total run-time.
7. To abort the fraction collection scheme at any time
during the program, press the Run/Stop key twice. The
pump will stop, and the LED display will read OFF,
indicating abortion of the fraction collection program.
Note: When a program is aborted, it can only be restarted
from the beginning.
8. To place a collection program that has begun on Hold,
press the lit Program Run key once. The pump will stop
and the program will be held. To resume the collection
program, press once again. Pressing the Run/Stop key
while the program is on hold will abort the fraction
collection scheme.
9. When the fraction collection program is complete, the
pump stops and the display reads "END." Press any key
to return to the ready mode.
Notes on Fraction Collection:
1. After a fraction collection program has begun, the pump cannot be
turned off without terminating the fraction collection program.

2. During the Voperiod of the fraction collection scheme (as indicated by
the Voindicator light), the fraction collector is not active. To collect
fractions during this void volume period, cancel Voby pressing the
Fraction Collector key. The fraction collector will start, with the LED
display indicating the time-progression of the collection scheme.
3. When the fraction collector is disabled by pressing the Fraction
Collector key, the fraction collector carousel will advance one tube.
4. When the fraction collector indicator light on the pump is lit, the Model
2110 Fraction Collector will be put into remote mode. Only the
manual advance keys will be active, and the Model 2110 display reads
---.
5. The fraction collection control feature of the Model EP-1 Econo Pump
can be used to turn off the pump even if a fraction collector is not
connected. Simply enter 0 for fraction size. After confirming the V
t
value entered (the Vtlight will be lit solid), start the pump, if not
already running; then press the flashing Program Run key. The LED
display will show time elapsed. The pump will stop automatically when
the total run volume has been delivered.
Use of the Diverter Valve
The optional Model SV-3 diverter valve (catalog number 731-8235)
provides a means to divert the eluant stream from a fraction collector to a
waste receptacle or other collection device during a fraction collection
program. If the void volume function (Vo) of the collection scheme is
enabled with the diverter valve in place, the eluant stream will be diverted
away from the fraction collector during that period. When that period is
over, the eluant stream will be diverted to the fraction collector. Whenever
the diverter valve changes from waste to collect, or vice versa, an event
mark is generated. This will appear as a deflection on the chart recorder.
For connection of the diverter valve, see Figure 7.1.
15
Fig. 7.1. Connection of the Model SV-3 Diverter Valve.
7.2 Use of the Econo Pump with the Model 2128
Fraction Collector
The Econo Pump is capable of controlling the Model 2128 Fraction
Collector. The pump must be calibrated in order to run a fraction collector
program. See Section 6 for calibration instructions.
Use System Cable 15 (catalog number 731-8286) to connect the Econo
Pump to the Model 2128 Collector. If the SV-3 diverter valve is used,
connect it as shown in Figure 7.1. If the Model 2128 Diverter Valve is used,
connect one end of System Cable 3 to the diverter valve port on the Econo
Pump, and connect the other end to the mini-DIN port on the Model 2128
Fraction Collector. This cable transmits flow diversion information from
the Econo Pump to the collector. Program collection as demonstrated in
Section 7.1. For more information about the Model 2128 Fraction
Collector, consult the user manual.

7.3 Use of the Econo Pump with the BioLogic
System
The Econo Pump can be controlled by the BioLogic System and used
as a sample loading pump.
Note: The Econo Pump must have v2.12 software in order to accept
on/off commands from the BioLogic System. See Section 10.1 for
instructions on how to check the software version. If an upgrade is
required, contact your local Bio-Rad representative.
To connect the Econo Pump to the BioLogic, use System Cable 7
(catalog number 731-8267). Connect the mini-DIN end of the cable to the
AUX port of the Econo Pump, and make a bare wire connection to the AUX
port of the BioLogic Workstation (RED to port 6, BLUE to port 9).
To connect the wires to the AUX port of the BioLogic System, turn the
small flathead screwdriver counterclockwise to back out the screw. Insert
the bare wire into the port and turn the screwdriver clockwise to secure the
connection. Be sure to calibrate the pump and set a flow rate prior to using
the Econo Pump with the BioLogic System, since the BioLogic sends only
“on/off” commands to the Econo Pump. To program the Econo Pump as a
sample loading pump with the BioLogic System, refer to the BioLogic
System user manual.
Section 8
Cleaning and Maintenance
The Model EP-1 Econo Pump requires very little maintenance to assure
reliable operation. The procedures outlined below will insure maximum
pump life:
• Check tubing regularly for signs of cracking and wear. If any exist,
replace the tubing.
• For optimal tubing life, use a slow to medium pump speed. To increase
throughput, increase tubing size to obtain the desired output.
• When not in use, tubing should be removed from the pump to prevent
deformation of the tubing. Remove the platen and relax the tubing by
unhooking one end of the tubing from the tubing bracket.
• To prevent the formation of precipitates around the pump head and on
the membrane key panel, promptly remove any spills. Clean with
deionized water.

Operation of the Model EP-1 Econo Pump When
Connected to Other Instruments
The Model EP-1 Econo Pump provides a variety of output signals which
can be used to control the operation of non Bio-Rad fraction collectors, or
to communicate with non Bio-Rad UV monitors and recording devices.
Communication is accomplished through two standard 8-pin mini-DIN
sockets on the rear panel of the pump. The third socket is for the operation
of the Model SV-3 Diverter Valve (see Figure 4.2). Bio-Rad offers an
accessory breakout cable (System Cable 7), which has an 8-pin mini-DIN
connector at one end and loose wires on the other, for connection to other
