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. Polyethersulfone (PES) membranes Hydrophilic PES membranes are designed for stability in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than either PTFE or PVDF.
