Introduction
Fig. 2.1. Model 2110 Fraction Collector.
The Model 2110 Fraction Collector (Figure 2.1), shown with the
optional instrument dust cover, is designed to be used with gravity feed
columns, preparative electrophoresis and liquid chromatography systems.
The Model 2110 Fraction Collector will accurately collect up to 80
fractions, at a flow rate of up to 40 ml/min. The Model 2110 Fraction
Collector accepts standard 13 x 100 mm test tubes or, with an optional
adaptor, 1.5 ml micro test tubes. Tubes are advanced by a motor-driven
22
Page 7
carousel where tube changes are initiated upon reaching a predetermined
drop count (1-999 drops) or time interval (0.05-99.9 minutes), or upon
command from an external source.
The silicone drop former insures uniform drop size for accurate drop
count measurement. The drop former will accommodate either 1¼
1
¼16-inch inlet tubing, without the need for additional fittings.
The Model 2110 Fraction Collector is spill-proof and solvent resistant.
A drain tube at the rear of the case channels all spills to waste. The membrane front panel is sealed to the case and the carousel drive is positioned
in such a way that it will not be affected by spills.
Section 3
Unpacking and Voltage Conversion
3.1 Unpacking Instructions
Lift the instrument out of its packing by grasping the instrument case.
Do not lift by the drop arm. Remove the power cord and bag of accessories. Remove the fraction collector from its protective bag. Check off all
parts against the supplied packing list. You may want to retain the original packaging material in the event the instrument needs to be returned for
service. If repackaging is necessary, be careful to position the carousel so
that it is not resting against the motor drive gear.
8-inch or
Warning: The Model 2110 Fraction Collector is shipped in its 120 V
version. For 220 V operation, refer to the procedure below.
3.2 Voltage Conversion
Prior to connecting the power cord to the power entry module and
power mains, make sure the voltage indicated on the fraction collector
power entry module matches your line voltage. If it does not, use the
following procedure to make the conversion. (See Figure 3.1.)
1. Insure that the unit is disconnected from the wall socket.
2. Remove the fuse drawer with a small-blade screwdriver or similar tool.
3. Pull the fuse holder out of the fuse drawer and ensure that the voltage
shown in the window corresponds to the voltage you are using (100, 120,
220, 240 V ). To change the voltage, grasp the fuse drawer and withdraw
it (see Figure 3.1). Rotate the fuse drawer so that the voltage shown is cor-
rect, and reinsert it. The fuse holder is keyed and cannot be installed
improperly. The Model 2110 Fraction Collector uses 0.20 A fuses for
100/120 V operation, and 0.10 A fuses for 220/240 V operation.

Page 8
4. Reinsert the fuse drawer in the power entry module, with the locking
tab to the left. The voltage indicator will read right-side-up if the
drawer is oriented correctly. Push the fuse drawer in gently until it
snaps into place.
5. Connect the power cord to the power entry module and power mains.
6. There is no power switch on the fraction collector. When connected
to an AC power source, the Model 2110 Fraction Collector will come
on in the Stop or Set mode.

Instrument Set-Up
5.1 Tubing Installation
1. Insert the drop former, narrow end downward, into the drop arm,
pressing it firmly in the hole (see Figure 4.1).
2. Using a twisting motion, press the arm cap onto the drop arm to hold
the drop former in place.
3. Insure that the end of the inlet tubing is cleanly cut and not flattened
or deformed.
Insert tubing into the drop former, pushing down on the tubing until
the drop former starts to stretch. Do not use excessive force. Then,
gently pull out on the tubing until the drop former returns to its
original shape.
4. The inlet tubing may be routed through the tubing holder fitting at the
rear of the movable portion of the drop arm.

Fig. 5.1. Carousel installation.
10
Page 15
5.2 Carousel Installation
The Model 2110 Fraction Collector fills tubes from the outside of the
carousel inward. Load as many tubes as desired into the carousel, starting
at the outside end of the spiral and moving inward. The carousel need not
be fully loaded, since any eluant flowing after the last tube will drain
through the carousel into the well in the case and out the central drain tube
located at the rear of the instrument.
1. Swing the drop arm to the waste (rear) position by gently lifting and
rotating (Figure 5.1a).
2. Hold the carousel so that the notch in its outline is toward the rear of
the instrument.
3. Place the carousel on the pivot shaft, holding it about 1¼2" above its
seated position.
4. Push the carousel and the pivot shaft toward the rear of the
instrument, settling it down over the drive gear so that the gear is
trapped near the start of the spiral.
5. Holding the gear teeth free from engagement, turn the carousel counterclockwise until it stops against the gear (Figure 5.1b). Release the
carousel and it will spring into engagement on the drive gear.
Engagement may be confirmed by trying to move the carousel gently
(Figure 5.1c).
6. Check the alignment with the two positioning guides located on the
top front of the instrument case. The number corresponds to the first
tube that will be filled.
Swing the drop arm into the collect (front) position. Make sure the
drive gear is fully seated into the grooved underside of the carousel. This
automatically aligns the drop former over the first tube.
5.3 Collection Tube Installation
Load the carousel with up to eighty 13 x 100 mm test tubes. You may
find a tube which fits too tightly into the carousel. It is best to discard
these rather than risk breaking the tube upon installation. Tubes 39
through 53 are raised above tubes 1-38 to make tube removal easier.
To locate an individual tube in a carousel, find its number on the
angled flange. The tube is in line with the number and the center of the
carousel. The top row of numbers corresponds to the outermost row of
tubes, the middle row corresponds to the next row of tubes, and the bottom row to the innermost row of tubes. To divert a large amount of eluant
to waste at the beginning of a run, you can simply remove the first
11
Page 16
collection tube, and the eluant will flow through the carousel to waste out
the rear of the collector.
5.4 Waste Collection Port
All spills on the top of the case and carousel, as well as waste eluant
within the carousel, drain to a central waste-collection port at the rear of
the instrument case. From this port, a drain tube passes out through the
rear of the case. This tube may be directed into a waste-collection vessel,
or an extension tube may be attached to the provided barbed union fitting.
Note: To provide proper drainage, the waste-collection vessel must be
positioned so that the exit of the drain tube is no higher than the bot-
tom of the fraction collector case.
Section 6
Stand Alone Operation
This section describes the stand-alone operation of the Model 2110
Fraction Collector. Refer to Section 7 for information about connecting
the Model 2110 to the Model EP-1 Econo Pump, the BioLogic LP, the
BioLogic System, or Bio-Rad’s preparative electrophoresis systems..
6.1 Stop (Standby) and Run
The Model 2110 Fraction Collector powers up automatically in the
Stop or Standby mode, with the LED lit. When in the Stop mode, the
collection mode, either Time or Drops can be selected, and the time interval or number of drops to be collected per tube can be set. When in the
Run mode, the Arrow keys are inactivated.
6.2 Collection Modes
The Model 2110 Fraction Collector will collect fractions by counting
the number of drops or by a specified time interval per tube. The collection mode is selected using the key on the front panel. In either mode,
time and drop count are continuously monitored, so that you can switch
between the two collection modes, monitoring time and drop count since
the last tube advance.
12
Page 17
Drop Collection Mode
The fraction collector counts drops at flow rates up to ~5 ml/min. Drop
counting is performed by the sensor in the drop arm. If the flow rate exceeds
5 ml/ min., counting will not be accurate, and use of the Time mode is
recommended.
1. Plug the Model 2110 Fraction Collector into a
grounded wall outlet. The collector will power
up in the Stop, or Standby mode, with the
LED lit.
2. Press the Time/Drop key until the LED is
lit.
3. Select the number of drops to be collected per
collection tube by pressing the keys.
The LED display will display the number of
drops to be collected.
4. Insure that the carousel is in the desired position, and press the Run/Stop key to begin collection. The LED will be lit.
5. The fraction collector will reset the display to
‘0’ and begin counting drops up to the drop
limit set, and then advance. The display reads
‘A’ during each carousel advance.
13
Page 18
Time Mode
The fraction collector collects fractions at intervals of .01 minutes, for
times per tube in the range of .05 to 9.99 minutes, and at.10 minute intervals for times per tube in the range of 10.0 to 99.9 minutes.
1. Press the Run/Stop key until the LED is lit.
2. Press the Time/Drop key until the LED is lit.
3. Select the time interval per tube by pressing the
keys. The LED multi-display will display
the time interval selected.
4. Insure that the carousel is in the desired position.
Press the key to begin the program. The
LED will be lit.
5. The fraction collector will reset the display to ‘0’,
and begin counting time up to the set time interval, and then advance.
Note: When the Model 2110 Fraction Collector reaches the preset
time interval in a time mode collection scheme, it will collect one
extra drop prior to advancing. This minimizes the chance of a drop
falling between tubes during carousel advance. If the delay between
drops is greater than 5% of the preset time interval, the collector will
advance to the next fraction instead of waiting for one extra drop.
6.3 Operation without Direct Connection
to a System
The Model 2110 can be used in stand-alone mode with any system.
Simply set up the collector in time mode or drop mode and press “start”
at the initiation of the method.
Alternatively, a light-weight gravity feed column (such as 2 ml
Poly-Prep
®
columns, Econo-Pac®columns, and small Econo-Column
®
chromatography columns) can be connected directly to the Model 2110
Fraction Collector, avoiding the need for interconnecting tubing. A
two-way stopcock is used to make the connection and control eluant flow.

1. Attach the stopcock into the hole in the top of the drop arm. Position
the stopcock so that its handle overhangs the end of the arm and is free
to turn.
2. Attach the column to the stopcock, making sure both stopcock and
column are firmly connected.
6.4 Manual Advance
The Model 2110 Fraction Collector may be manually advanced to the
next tube by pressing the key. This key is functional in both
Stop/Standby and Run modes. When pressed during a run, the drop and
time counts will automatically reset to 0, and restart the time or drop
count.
6.5 Reset/End of Run
If the Model 2110 Fraction Collector is allowed to complete 80
advances, the display will read END. To reset, push twice. (Note:
Manual advances are not counted.) Reposition the carousel to begin
collection again.
Section 7
Remote Operation of Model 2110
The Model 2110 Fraction Collector may be controlled remotely.
7.1 Remote Operation with Model EP-1 Econo
Pump
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 Econo Pump manual if further
explanation is required.) In order for the Econo Pump to remotely operate
the Model 2110, a method must be programmed into the Econo Pump that
calls for fraction collection. You will be prompted to program the fraction
size (volume), the void volume, and the total volume collected. Please
note that to correctly use the void volume function, a Model SV-3
Diverter/Bypass valve (catalog number 731-8322) must be connected.
When programming is complete, the LED display underneath the fraction
collector icon on the front panel of the Econo Pump will light and the
Model 2110 display will read “---” indicating that the collector is
controlled by a system.
15
Page 20
7.2 Remote Operation with BioLogic LP
Use System Cable 1 (catalog number 731-8261) to connect the
BioLogic LP 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
BioLogic LP controller in the port marked FRACTION COLLECTOR.
(See BioLogic LP manual if further explanation is required.) The
BioLogic LP enables sophisticated collection, including programmed
collection windows, peak detection, and a combination of peak detection
and collection windows. The BioLogic LP sends “advance” commands to
the fraction collector.
7.3 Remote Operation with BioLogic System
Use System Cable 5 (catalog number 731-8265) to connect the
BioLogic System to the fraction collector. Connect the 9-pin “D” connector to rear of the Model 2110. Connect the black wire to the FC ADV port
of the AUX connector, which is port #5. Connect the white wire to the
GND port of the AUX connector, which is port #9. Refer to the separate
instruction sheet for the wiring diagram and color code for System Cable
5.
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. The BioLogic System enables sophisticated
collection, including programmed collection windows, peak detection,
and a combination of peak detection and collection windows. The
BioLogic System sends “advance” commands to the fraction collector.
7.4 Remote Operation with other Instruments
Use System Cable 5 (catalog number 731-8265) to connect the Model
2110 Fraction Collector to other instruments. Signals are accessible via
the 9-pin “D” connector on the back of the instrument. All of the input and
output signals, with the exception of the Advanced Contact pins 7 and 8,
are TTL active low.
Drop counting is performed by the sensor in the drop arm.

9 Logic Ground
External Advance (Pin 1)
The External Advance line performs two functions. It causes the
instrument to enter the Remote mode when held low for longer than two
seconds, and it causes the carousel to advance one position each time a
high-going pulse is applied. To use the control line to advance the
carousel, connect pin 1 of the 9-pin “D” connector to pin 9 and hold for
at least 100 msec, then release. Alternatively, the carousel will advance by
applying an external signal (TTL low logic level ) to pin 1 for at least 100
msec (with a return to TTL high logic level state). Be sure to connect the
controlling instrument’s ground to the fraction collector’s logic ground,
pin 9. When remote mode is entered (by holding pin 1 low for greater than
2 seconds) the time and drop mode features of the collector are disabled
and the front panel control function is lost, with the exception of the manual tubing advance key, which will function normally. The remote mode
is indicated by three horizontal bars on the fraction collector display.
Drops
The fraction collector will generate a 50 msec TTL pulse on pin 2
every time a drop is detected.
Advanced
Each time the carousel is advanced, a low-going TTL pulse is generated on pin 3. This signal is useful for triggering the event mark input of
a chart recorder to indicate fraction intervals. If the recorder being used
does not support TTL signals, then see below under “Advanced Relay
Contacts to trigger the event input.
Ready
A low level signal on pin 4 indicates that the fraction collector is functioning properly and that it is ready to accept input from a controlling
device.
Alarm
If the fraction collector is unable to carry out an external advance
command due to a malfunction (such as a jammed carousel), a low level
will be held on pin 5 until the problem is cleared.
17
Page 22
External Start
The external start line is used to allow another instrument to remotely start and stop the fraction collector’s programmed functions. Applying
a low pulse of at least 100 msec to pin 6 has the same effect as pressing
the Run/Stop key on the front panel. That is, the first pulse will start the
previously selected mode (drops or time) and the second pulse will stop
the program.
Advanced Relay Contacts
Pins 7 and 8 provide a normally open set of contacts that are momentarily closed each time the carousel is advanced. This signal is a convenient way to interface with equipment that does not support TTL level signals. The maximum current and voltage which can be put across these
pins is 24 V DC and .25 A.
SSeeccttiioonn 88
AAcccceessssoorriieess
8.1 Instrument Dust Cover
The dust cover (catalog number 731-8136) is intended for use only
when the drop arm is in the collect (forward) position. The inlet tube may
be directed out the top opening or through the small opening at the bottom/rear of the instrument.
8.2 Micro Tube Adaptor
The micro tube adaptor is intended to convert a carousel for use with
1.5 ml micro test tubes (catalog number 223-9500).
Align the step in the outline of the adaptor with the step of the outline
of the carousel. Position the adaptor so that its four legs fit into the four
openings in the inner wall of the carousel. Push the adaptor downward
until it is fully seated on the carousel.
Operation with micro tubes is identical to operation with standard test
tubes. To prevent splashing, collect no more than 1 ml of eluant in each
micro tube.
18
Page 23
Section 9
Cleaning and Maintenance
The Model 2110 Fraction Collector requires very little maintenance to
insure reliable operation. Two procedures are outlined below.
9.1 Drop Sensor
The Model 2110 Fraction Collector counts drops through an optical
sensor located in the drop area inside the drop former arm. Precipitates or
other foreign debris may obscure the optical path and cause erroneous
drop counts. To prevent this problem, the drop sensor should be cleaned
periodically. An ordinary cotton swab moistened with water can be used
to clean the sensor.
9.2 Instrument Case, Carousel, and Drainage Tube
During normal operation, spills and splashes may result in precipitates forming on the case and carousel. Use a squirt bottle and soapy water
to wash down carousel and case. The water will drain out the back of the
unit through the drainage tube. Prior to squirting the instrument case,
make sure the rubber seal around the gear device is in place. Insure that
the waste tube is draining properly to avoid instrument damage.

Model 2110 Fraction Collector
Procedure for Adjusting Drop Detector
Signal Level
This procedure should be performed:
1. After replacing the drop arm on the Model 2110 Fraction Collector.
2. Whenever "EO8" is displayed. In this situation, clean the optical window
and light source prior to performing this procedure.
Safety: The Model 2110 Fraction Collector should be purged of all hazardous
chemicals and be disconnected from the main power supply prior to conducting this procedure. Ensure the case is dry. Perform this procedure on a dry surface. During the actual adjustment of the signal level (step 10), potentially
dangerous voltages are present inside the case - do not touch exposed wires.
Use a plastic-handled screwdriver to minimize the risk of electric shock.

Tools required: Small phillips-head screwdriver, small slot-head screw
driver.
Procedure:
1. Disconnect the Model 2110 collector from the power source.
2. Disconnect any tubing leading to the fraction collector, remove the yellow
plastic arm cap, white rubber drop former, and carousel.
3. Clean the optical window and light source (located in drop arm), using the
a cotton swab moistened with water.
4. Set fraction collector on its side with underside of the instrument facing
toward you.
5. Remove the four phillips-head screws from the underside of the instrument. Pull gently on the rubber feet to remove the underside panel.
6. Locate the large circuit board with the power transformer. On this board,
locate a small rectangular potentiometer, identified as "R3" on the circuit
board. R3 is located near where the ribbon cable connects to the circuit
board.
7. Read safety warning above. Use a plastic-handled screwdriver to min-
imize the risk of electric shock.
8. Press and hold down both the "up" and "down" arrow keys on the front
panel.
9. While continuing to press down arrow keys, connect the fraction collector to the power source. Continue to press down both keys for five seconds, then release.. The "time" LED will glow steadily, and the display
will show a decimal point, followed by three characters (._ _ _). The fraction collector is now in a "diagnostic" mode.
10. Using a small flat-bladed screwdriver, adjust R3 by turning the small
screw until the display reads between "0A0" and "0A5".
If a reading between "0A0" and "0A5" cannot be obtained, contact your
local Bio-Rad representative.
11. Disconnect unit from the power source.
12. Replace underside panel.
13. Connect fraction collector to a power source. The Model 2110 Fraction
Collector is now ready for operation.
