Memtrex PM (MPM) filters' 100% polypropylene construction offers low extractables, long service life and broad chemical compatibility (Figure 1). Thermoplastic sealing techniques are used in the cartridge construction eliminating the need for glues or sealers which could leach contaminates. MPM filters are integrity testable. All components are made of FDA-acceptable materials and meet the test criteria for the USP24 Class VI 121ºC plastics.

MPM filters utilize high flow polypropylene membranes, capable of protecting your gas, air, and liquid processes with absolute ratings of 0.1 and 0.2 micron. GE Water & Process Technologies is your complete source for filters, crossflow membranes, housings and other filtration equipment.

    Additional Information

    N/A

    • Memtrex PM filters may be autoclaved or in situ steam sterilized (up to 253ºF [123ºC], 30 minute cycles) for a maximum accumulated exposure of 10 hours. Alternatively, the filters may be sanitized with compatible chemical agents.
    • GE certifies that the materials contained in its Memtrex PM pleated filters meet U.S. FDA requirements for food contact under the applicable regulations in 21 CFR. For further information, contact the GE technical services. Memtrex PM filters meet the test criteria for USP class VI-121ºC Plastics.
    • Aqueous extracts from Memtrex PM filters contain less than 0.25 EU/ml. The filters typically exhibit low levels of non-volatile residues. GE filter cartridges are designed and manufactured for resistance to a wide range of chemical solutions. Conditions will vary with each application and users should carefully verify chemical compatibility. Please contact your GE distributor for more information.
