Industry’s Filtration Partner
Memtrex MP-E (MMP-E) filters (Figure 1) incorporate a modified asymmetric Polyethersulfone membrane with polypropylene supports and hardware for enhanced service life and cleanliness in UPDI water and other microelectronics applications.

The Electronics (E) Grade Memtrex-MP-E filters are manufactured utilizing a high-purity rinse on each and every filter to reduce TOC and trace metals below 5.0 ppb. This is ideal for final filtration on Dl water pads and POU applications. These filters are also 100% integrity-tested to ensure reliable particle retention.

The MMP-E filter is just one example of our strong commitment to the electronics industry. Our complete portfolio includes filters for every stage of processing, and we offer custom solutions for your unique applications. GE Water & Process Technologies is your complete source for filters, crossflow membranes, housings and other filtration equipment.

    N/A Memtrex MP-E filters are available the following absolute pore size micron ratings: 0.03, 0.1 and 0.2 µm. Tables 1, 2, 3, 4 and 5 show further details on materials of construction, dimensions, operational limits, integrity testing and flow performance.

    Additional Information


    • Memtrex-MP-E filters with polypropylene components may be autoclaved (121ºC, 30 minute cycles) or in situ steam sterilized (125ºC, 30 minute cycles) for a maximum accumulated exposure of 10 hours. Memtrex-MP-E filters with polyethylene hardware must not be autoclaved or in situ steam sterilized. Alternatively, the filters may be sanitized with compatible chemical agents.
    • The component materials of Memtrex-MP-E filters are suitable for use in articles intended for repeated food contact as specified in the United States Code of Federal Regulations, Title 21. Memtrex-MP-E filters meet the test criteria for USP24 class VI-121ºC Plastics and pass the MEM Elution Cytotoxicity Test.
    • Aqueous extracts from Memtrex-MP-E filters contain less than 0.25 EU/ml. The filters typically exhibit low levels of non-volatile residues. The filters rinse to less than 5 ppb TOC and less than 5 ppb trace metals in 25 min at 2.5 gpm per 10" module in UPDI water.
