and buffer select valves, UV and Conductivity Flow Cells, and other devices used with the
system. The optional BioLogic Rack Expansion kit is available to extend the rack to 3
trays.
Proportioning This combination of valve and mixer module mixes and proportions two buffers.
Valve/Mixer It is designed to be rack mounted or free-standing.
Module
UV Detector This consists of the UV Optics Module and the control circuitry within the BioLogic LP
Controller. The UV Optics Module includes a mercury lamp and filters for fixed wavelength UV detection at 280nm and 254nm. The flow cell has a path length of 2 mm, an
internal volume of 80 µl, and an illuminated volume of 3µl.
Conductivity This consists of the Conductivity Flow Cell and the control circuitry within the BioLogic LP
Detector Controller. The Conductivity Flow Cell provides instantaneous, on-line readings of con-
ductance for monitoring a salt gradient and optimization of column chromatographic conditions.
Valves Valves for the BioLogic LP include:
• MV-6 Inject Valve
• SV-5 Buffer Select valve
• SV-3 Diverter/Column Bypass valves
Sample Loops Tygon tubing sample loops are prepared by the user.
Fraction Fraction collectors are controlled by the BioLogic LP Controller via the Fraction Collector
Collector port. Fraction advance marks (event marks) are embedded in the UV signal sent from the
Controller to a chart recorder. The following fraction collectors are supported:
• The Model 2128 provides X-Y motion drop dispensing. The Model 2128 accommodates a
wide range of tube diameters and lengths, microtiter plates, micro-tubes, and “bottle size”
fractions. The Model 2128 is ideally suited for both analytical and preparative applications.
• The Model 2110 uses a stationary drop-dispensing head to collect up to 80 fractions in a
carousel. The SV-3 Diverter valve is required for full operation. The Model 2110 is controlled by the BioLogic LP Controller via the Fraction Collector port.
• Generic fraction collectors may be used with the BioLogic LP as long as tube advances
can be initiated by a TTL pulse (active high or active low, 100 ms duration.) The SV-3
Diverter valve is required for full operation.
Regardless of which fraction collector is chosen, fraction time/volume and collection parameters such as Collect All, Collection Windows, Threshold, and Threshold
+ Collection Windows are controlled from the BioLogic LP Controller.

2.3 UV DETECTOR
The UV Detector, which consists of the UV Optics Module and the control circuitry within the BioLogic LP
Controller, is a single beam, fixed wavelength UV absorbance detector specifically designed for protein chromatography. The UV Optics Module can be positioned close to a column outlet, minimizing system dead
volume and remixing of peaks. When connecting the UV Optics Module to the system, note the flow direction arrows on the top of the UV Optics Module’s case. It is important that the flow direction through the flow
cell is correct.
Figure 3. UV Optics Module
The AU readings from the BioLogic LP UV detector will not correspond directly to absorbance readings from
a spectrophotometer. The primary reason for this is the different path lengths; light bandwidths and other
factors have an effect as well. This has no effect on the UV monitor’s ability to detect protein.
Eleven fixed UV absorbance ranges, from 5.0 to .001 Absorbance Units Full Scale (AUFS), are available.
The user may choose a “custom” range using the “Set Max” function. Refer to Table 9.
The UV Optics Module consists of a low pressure mercury lamp, 280nm and 254nm filters, and a flow cell.
The filters are both held by a single tray. The flow cell, which uses luer fittings, has a 2 mm path length. It
has an internal volume of 80 µl and an illuminated volume of 3 µl.
The UV Optics Module receives power from the BioLogic LP Controller, to which it is connected by the UV
Lamp cable. The UV detector communicates with the system via the UV Optics cable, which plugs into the
UV Optics connector on the back of the BioLogic LP Controller.
FLOW CELL
FILTER HOLDER
AND FILTERS
UNDERSIDE OF
UV OPTICS MODULE
Figure 3 shows how the flow cell and the filters can be changed. To remove the flow cell, you will need to
remove the retaining clip from the bottom of the optics module and pull the luer connectors away from their
holders. Then loosen the thumbscrews and remove the flow cell. When inserting the replacement flow cell,
make sure the O-ring is securely placed on the flow cell. To change the filter, loosen the filter’s thumbscrew
and lift out and rotate the filter holder. The selected wavelength is indicated by the raised arrow on the bottom of the case.
WARNING: To avoid exposure to UV radiation, turn off the UV lamp when changing filters and flow cells.
2.4 CONDUCTIVITY DETECTOR
The Conductivity Detector consists of a small, portable Conductivity Flow Cell and the control circuitry which
resides in the BioLogic LP Controller. This monitoring system provides a means to check equilibration conditions and the formation of a salt gradient, for example, in ion-exchange chromatography and hydrophobic
interaction chromatography. This data helps in optimizing purification protocols and column cleaning procedures.
Figure 4. Conductivity Flow Cell and Separate Holder
The Conductivity Flow Cell consists of the following:
• Flow cell with Inlet/Outlet ports: For connection of the tubing, using luer fittings. The flow cell allows
flow in either direction.
• Signal Cable: For connection to the back of the BioLogic LP Controller. Electrical power for the
Conductivity Flow Cell is drawn off the signal cable.
The flow cell can be plumbed immediately after the UV Optics Module’s flow cell or at any other point in the
flowpath. Aseparate holder for the Conductivity Flow Cell is mounted to the system rack. The swept volume in the cell is a nominal 2 µl.
Conductivity is measured in milli-Siemens (mS). For accurate measurement, the flow cell must be calibrated. Refer to Table 10.
Nine fixed Conductivity ranges, from 500 to 0.5 mS Full Scale (mSFS), are available. The user may choose
a “custom” range using the “Min/Max” function. Refer to Table 10.

2110 is inactive while the fraction collector is under the control of the BioLogic LP. Only the fraction collector’s Advance key is active during this time.
The SV-3 diverter valve is required by the Model 2110 when doing any collection scheme other than “Collect
All.” The SV-3 diverts flow away from the fraction collector when fractions are not being collected.
Collection parameters such as Collect All, Threshold, Collection Windows, and Threshold + Collection
Windows become available in Program mode.
The Model 2110 is plumbed to the BioLogic LP using Tygon tubing. The Tygon tubing is inserted directly
into the fraction collector’s drop former, without the need for additional fittings.
The Model 2110 fraction collector is described in detail in its separate documentation.

2.5.2 Model 2128 Fraction Collector
The Model 2128 provides X/Y motion drop-dispensing, accommodating a wide range of tube diameters and
lengths, microtiter plates, microtubes, and “bottle size” fractions. It is ideally suited for both analytical and
preparative applications.
Figure 6. Model 2128 Fraction Collector
The Model 2128 is connected to the BioLogic LP Controller via the following cables:
• System Cable 15: This is required whenever the Model 2128 is to be controlled by the BioLogic LP
Controller. It transmits the “Advance” commands. (Note: Only three of the 15 pins on the D-connector are used.)
• System Cable 3: This is required when the Model 2128’s arm-mounted diverter valve is used, or
when no diverter valve is used. This cable transmits the “Collect/waste” commands from the
BioLogic LP, which tells the fraction collector when to move the drop head to the waste trough, or
when the optional arm-mounted diverter valve is to switch between collect and waste.
When connected as described above and place in its ECONO mode, the Model 2128 is controlled by the
BioLogic LP Controller. Collection and tube advance is controlled by the BioLogic LP. Programming mode
supports the following collection schemes: Collect All, Threshold, Collection Windows, and Threshold +
Collection Windows (all with Delay volume, if desired). The Model 2128’s optional diverter valve mounts on
the collector’s arm and minimizes liquid spills during fraction advances.
The Model 2128 is plumbed to the BioLogic LP Controller using Tygon tubing and either of the following fittings:
• To connect directly to the drop head, use the luer adaptor (provided with the Model 2128 Fraction
Collector) to adapt the Tygon tubing from the BioLogic LP to the 1/16” tubing leading to the drop
head.
• To connect to the optional arm-mounted diverter valve, use the luer adaptor (provided with the
Model 2128) to adapt the Tygon tubing from the BioLogic LP to the 1/16” tubing leading to the
“Common” port of the diverter valve.
This instrument is described in detail in its separate documentation.

2.5.3 Model 1327 Chart Recorder
When used with the BioLogic LP, the Model 1327 Chart Recorder automatically starts when a method
begins and stops when the method ends. The BioLogic LP’s Manual mode operation of the chart recorder
may be used to start and stop the chart recorder.
The following cables are required to connect the Model 1327 Chart Recorder to the BioLogic LP Controller:
• System Cable 2: Through this cable, the BioLogic LP outputs the UV analog data signal, pen
up/down, and Stop/Start commands to the Model 1327 chart recorder. It connects to the BioLogic
LP’s UV Chart port and to the chart recorder’s DIN connector.
• System Cable 4: Through this cable, the Conductivity analog data signal is sent from the BioLogic
LP to the Model 1327 Chart Recorder. The cable connects to the BioLogic LP’s Cond Chart port
and to the chart recorder’s channel 2 banana plug connectors.
• Power cable and adapter: Operating power for the Model 1327 Chart Recorder is supplied via the
jack next to the chart recorder’s DIN connector. (Note: The Model 1327 Chart Recorder may also
be run on batteries.)
Figure 7. Model 1327 Chart Recorder
In addition, following chart recorder controls should be set:
• All chart recorder controls with a green setting should be set to their green setting.
• Paper speed dial: Select a chart speed appropriate for the separation being performed.
• Manual paper feed: Using this switch, select Paper “fast feed” to quickly advance the paper to the
desired position.
• Baseline adjustment dial: These dials allow for pen position adjustment. The “zero” position of each
pen is adjusted using the thumbwheel for each channel. When adjusting the pen’s zero position,
make sure that the BioLogic LP instrument (UV or Conductivity Monitor) is zeroed first.
Note: The chart speed is set at the recorder itself. The BioLogic LP Controller does not control this
function.
This instrument is described in detail in its separate documentation.

2.6 NON-BIO-RAD SYSTEM OPTIONS
Non-Bio-Rad fraction collectors and chart recorders may be used with the BioLogic LP, as discussed in the
following sections.
Figure 8. Pin Assignments for BioLogic LP’s Fraction Collector and Chart Recorder Connectors
2.6.1 Non-Bio-Rad Fraction Collectors
A non-Bio-Rad collector may be used with the BioLogic LP, providing its tube advance function can be initiated by a TTL signal with a duration of 100 milliseconds or greater.
Use System Cable 7 to connect a non-Bio-Rad fraction collector. Pin-outs for the BioLogic LP’s Fraction
Collector port are listed below and shown in Figure 8. Pin 5 is the TTL control wire, and pin 7 is the logic
ground. Awire color to pin number chart is included with System Cable 7. See the pin-out information in
your collector manual.
• Pin 1: The function of this pin differs, depending on your selection in Manual mode operation of the
fraction collector. (See Table 7, Manual Mode Operation: Fraction Collector for details on selecting a
fraction collector.) Manual mode offers the following selections:
Other or 2128: The BioLogic LP software allows you to select “Other” when indicating a non-BioRad fraction collector. (Selecting 2128 functions similar to Other.) In this mode, this pin is normally
“low” (0 volts). It goes “high” (5 volts) for 100 milliseconds when a tube change is commanded.
2110: When the Model 2110 fraction collector is selected, this pin is normally “high” (5 volts). It
goes “low” (0 volts) for 100 milliseconds when a tube change is commanded.
• Pins 2 - 4: Not connected.
• Pin 5: The function of this pin differs, depending on your selection in Manual mode operation of the
fraction collector. (See Table 7, Manual Mode Operation: Fraction Collector for details on selecting a
fraction collector.) Manual mode offers the following selections:
Other or 2128: When Other (or Model 2128) fraction collector is selected, this pin is normally
“high” (5 volts). It goes “low” (0 volts) for 100 milliseconds when a tube change is commanded.
2110: In this mode, this pin is normally “low” (0 volts). It goes “high” (5 volts) for 100 milliseconds
when a tube change is commanded.
• Pin 6: Not connected.
• Pin 7, Digital Ground: This is the “ground reference” pin for all control inputs and outputs on this
connector.
• Pin 8, Event Mark In: This pin is normally high (5 volts). When an external device such as a frac-
tion collector pulls it “low” for 100 milliseconds or more, the BioLogic LP generates an event mark on
the analog output to the Chart Recorder’s channel 1.

If you are using a non-Bio-Rad fraction collector, use an SV-3 diverter valve to enable advanced features
such as collection by Threshold and/or Collection Windows. If this optional valve is not used, then only
Collect All is available.
2.6.2 Non-Bio-Rad Chart Recorders
A non-Bio-Rad chart recorder may be used with the BioLogic LP. A mini-DIN to banana plug cable (System
Cable 4) is used to connect the BioLogic LP Controller ’s UV Chart port to the chart recorder. The input sig-
nal voltage should be set to 1V for both BioLogic LP UV and Conductivity signals.
The pin outs for the BioLogic LP’s UV Chart port are listed below and shown in Figure 8:
• Pin 1, Stop Paper: This pin is high (5 volts) when a method is running or when the BioLogic LP’s
Manual mode is used to make the chart recorder run. When the method ends, or Manual mode is
used to stop the chart recorder, the BioLogic LP pulls this pin “low” (0 volts) and the chart paper
stops feeding.
• Pins 2 and 3: Not connected.
• Pin 4, Integrator (+): This pin sends an unfiltered, unscaled signal to integrators or other data
acquisitions systems. An absorbance of 2 AU will cause a 1 volt signal at this pin, regardless of UV
Monitor range settings. When using this output, connect the negative lead to pin 7, Analog ground.
• Pin 5, Chart Recorder (+): This pin is connected to the positive lead of the chart recorder channel
1, which displays the UV absorbance trace. This signal is 0 volts when the UV Monitor reads 0 AU,
and 1 volt when the UV monitor reads “full scale”.
• Pin 6, Pen Lift: This pin is “low” (0 volts) when a method is running, or when the BioLogic LP
Manual mode is used to make the chart recorder run. When the BioLogic LP allows this pin to go
“high”, the pens lift from paper.
• Pin 7, Chart Recorder (–), analog/digital ground: This pin is connected to the negative lead of
the chart recorder channel, which displays the UV absorbance trace. It also serves as the negative
lead for the integrator signal and the negative connection for all digital signals on this connector.
• Pin 8: Not connected.
The pin outs for the BioLogic LP’s Cond Chart port are listed below and shown in Figure 8:
• Pins 1 – 4: Not connected.
• Pin 5, Chart Recorder (+): This pin is connected to the positive lead of the chart recorder’s chan-
nel 2, which displays the conductivity trace. This signal is 0 volts when the Conductivity monitor
reads the programmed “minimum” conductivity value, and 1 volt when the conductivity monitor reads
the programmed “maximum” value.
• Pin 6: Not connected.
• Pin 7, Chart Recorder (–), analog ground: This pin is connected to the negative lead of the chart
recorder’s channel 2, which displays the conductivity trace.
• Pin 8: Not connected.

3.0 SYSTEM CONNECTIONS
When setting up the system, consider the amount of bench space available, the instruments to be used with
the system, and the devices to be used with the System Rack.
The BioLogic LP can be set up wherever there is available bench space and sufficient power outlets, including in 4° cold rooms or cold boxes. When used in a cold environment, it is recommended that you leave
system power “ON” to minimize condensation.
All BioLogic LP systems will include as a minimum the following:
• Controller • Proportioning valve/Mixer module
• System Rack (single tray configuration) • MV-6 Inject Valve
• UV Optics Module • Fittings kit
• Conductivity Flow Cell • Tubing
Your BioLogic LP system may include components or instruments not listed above. Refer to the separate
supporting documentation for each of the following types of devices:
• Bio-Rad Model 2128 or Model 2110 Fraction Collector
• Bio-Rad Model 1327 Chart Recorder
• additional valves
• instruments not purchased from Bio-Rad, such as a generic fraction collector or chart recorder

To set up the BioLogic LP System:
1. BioLogic LP Controller.
a. Place the BioLogic LP Controller on the bench and turn the unit so that the back side faces you.
b. Connect the power cable. Do not turn on the unit.
2. System Rack.
Assemble the Rack and place it on the BioLogic LP Controller, as described below.
a. Fit the tapered collars into the ringed grooves on the rods. The collars are tapered so that when
they are attached to the rods and the rods are fitted into the holes at each end of the tray, the rods
and collars serve as the legs of the tray. With this in mind, note the following guidelines:
• The long rods have several grooves. Attach the collars to the groove closest to the end of
the rod. Attach the collars so that the taper is toward the end of the rod.
• The short rods each have only one groove. Fit the collars onto the grooves so that the collars flare out toward the farthest end of the rod. Refer to Figure 10.
b. Insert the two long rods into the holes at the back of the tray, as shown in Figure 10.
Note: The rods are inserted from underneath the tray such that they produce a firm fit in the holes.

4.0 SYSTEM PLUMBING
This chapter begins with discussion of plumbing practices and general guidelines, followed by a general procedure for plumbing the major system components. Later sections discuss how to plumb Bio-Rad’s low
pressure valves.
4.1 GENERAL GUIDELINES FOR PLUMBING THE SYSTEM
The BioLogic LP uses the following tubing:
• System tubing: 0.8mm ID or 1.6mm ID Tygon tubing.
• Pump Tubing: 0.8mm ID, 1.6mm ID, or 3.2mm ID PharMed tubing. Refer to the following table
when selecting a tubing.
Warning
Do not use pump tubing with wall thickness greater than 1.0 mm. Using tubing with a wall thickness
greater than 1.0 mm can damage the pump and void the warranty.
