Bio-Rad BioLogic LP System - Manual (Page 9)

1.2 FEATURES
The BioLogic LP System provides the following features:
• A space-saving modular and stackable design which minimizes the system footprint on the bench.
• Programming separation methods is menu-driven, easy and intuitive using either Time-based or
Volume-based steps. Method storage capacity easily meets most laboratory requirements.
• On-screen help function.
• Single-point control of pump, UV and Conductivity monitors, chart recorder, fraction collector, valves,
and timer.
• Dynamic mixing for accurate and reproducible gradient formation.
• The use of biocompatible materials throughout the flowpath to ensure maximum recovery of biologi-
cal activity.
• Operation at 280nm and 254nm, with a preparative UV flow cell
• Standard conductivity cell to monitor gradient formation.
• Four Fraction Collection schemes are standard. Collection is volume-based or time-based with
Collect All, Collection Windows, Threshold and Threshold + Collection Window modes. A wide
range of fraction collectors may be used, including Bio-Rad’s Model 2128 and Model 2110 fraction
collectors.
• Software control of diverter, column bypass, and buffer select valves.
• Sufficient tray space on the basic System Rack to hold a Model 2110 Fraction Collector or a Model
1327 Chart Recorder. Additional rack components are available to make a three-tray configuration.
• System Rack includes column supports to eliminate rack clutter.
