Eight different material options Choice of 4 mm, 13 mm, and 30 mm syringe filter diameter to suit sample volume Range of pore sizes for retaining a variety of particles Optional sterile, medical grade blister pack Optional tubetip format for accurate dispensing into a microvial Whatman Puradisc syringe filters from Cytiva's business combine premium quality with economic efficiency. They are well suited for rapid, routine syringe filtration of samples up to 100 ml. Puradisc syringe filters for routine syringe filtration Puradisc syringe filters cater to a wide variety of sample types and applications, including capillary electrophoresis, biological preparations, protein filtration, and UV spectroscopy sample preparation. Different Puradisc membrane media support diverse chemical solvents and compounds.
Puradisc is available in the following membrane materials: regenerated cellulose (RC), cellulose nitrate, nylon, polytetrafluoroethylene (PTFE), polyethersulfone (PES), polypropylene, polyvinylidene difluoride (PVDF), and cellulose acetate.
Cytiva's Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. Cytiva also offers highperformance GD/X syringe filters with a multilayer glass fiber prefilter for filtering larger volumes of hardertofilter samples. Glass microfiber (GMF) membranes Glass microfiber is hydrophilic and has excellent compatibility with organic solvents and strong acids (except hydrofluoric acid) and bases. However, it is not a micropore membrane and so has a slightly less exact retention efficiency than polymeric membranes. GMF can also contribute extractables that interfere with ionic and metals analysis.
