2.5 BIO-RAD SYSTEM OPTIONS
Bio-Rad offers a number of system options for use with your BioLogic LP. The following instrument options
are described in this section.
• Models 2110 and 2128 Fraction Collector
• Model 1327 Chart Recorder
2.5.1 Model 2110 Fraction Collector
The Model 2110 collects up to 80 fractions in a motor-driven carousel. It uses standard 13 x 100 test tubes.
An optional adapter is available for use with 1.5 ml microcentrifuge test tubes.

(Dust Cover is optional)
The Model 2110 is connected to the BioLogic LP Controller via System Cable 1. When controlled by the
BioLogic LP Controller, fraction collection is by time or volume. The numeric display screen on the Model
2110 is inactive while the fraction collector is under the control of the BioLogic LP. Only the fraction collec-
tor’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.
