Sterilizing Grade PVDF0.2 Micron Membrane Filter Cartridge

SERENE PVDF pleated cartridge filters are uniquely constructed with polyvinylidene fluoride media. PVDF membranes offer broad chemical compatibility with low extractable levels, high protein binding and high chemical inertness. The pleat technology maximizes the useful surface area of the filter while maintaining proper flow paths between media pleats. These cartridge filters are manufactured with PVDF and polypropylene support media, both materials are chemically inert non-shedding and biologically safe according to FDA, USP and EEC requirements for pharmaceutical and food contact use. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives.

The hydrophilic polyvinylidene fluoride (PVDF) membrane filter is available in discs, capsules, high capacity Mega capsule, and cartridges with 0.1 µm, 0.2 µm, 0.4 µm and 0.6 µm absolute ratings. It is optimized for the clarification, prefiltration and sterile filtration of liquids. Manufactured by a state-of-the-art process, the filter provides the highest flow rates of any PVDF filter.
