The BioFrac™ fraction collector, ideal for analytical and preparative chromatography applications, is 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. The custom racks provide a wide range of collection capability, from drops to liters. Off-the-shelf racks extend the versatility of collection schemes and provide cost-effective storage of samples. Off-the-shelf racks are autoclavable, can be easily assembled, and lie flat, using little storage space.
