2.7 FRACTION COLLECTORS
The DuoFlow features several options for fraction collection:
• BioFrac fraction collector
• Model 2110 fraction collector
• Model 2128 fraction collector
• Non-Bio-rad fraction collectors
The BioFrac fraction collector, the Model 2110 fraction collector, and the Model 2128 fraction collector are
programmable and can be run via BioLogic software version 4.0 or higher.
2.7.1 BioFrac Fraction Collector
The BioFrac functions with the BioLogic DuoFlow system and as a stand-alone fraction collector with the
BioLogic HR and non Bio-Rad chromatography systems. It is suited for both analytical and preparative
applications.
Figure 2-19. BioFrac Fraction Collector
Features of the BioFrac include:
• It can be used with any chromatography system at flow rates up to 100 ml/min.
• It can collect in time, drop or volume mode (time and drop mode are only available in stand-alone
mode).
• A diverter valve, mounted on either side of the vertical bars, diverts unwanted eluant to waste.
• Can be fitted with an optional drop former (25 µl drops) designed for collecting small sample sizes.
