The BioFrac Fraction Collector is ideal for analytical and preparative chromatography applications; it's easy to program and can be used for basic or complex fraction collection schemes at flow rates ≤100 ml/min. Available as a stand-alone fraction collector or as a component of the BioLogic DuoFlow™ and BioLogic™ LP Chromatography Systems, the BioFrac Fraction Collector offers flexibility with numerous collection rack options, including both custom and off-the-shelf collection racks.
