The BioLogic rack is an adaptable racking system made of durable, solvent-resistant polypropylene, stainless steel, and glass-filled nylon. The rack can stand alone or be combined with any BioLogic DuoFlow or BioLogic LP chromatography system to save benchspace. It supports a range of columns and cartridges, valves, detection modules, buffer bottles, and peripheral equipment (such as the Model 2110 fraction collector). A BioLogic rack expansion kit and optional rack components are available for custom racking applications.
