Typical Applications

MMP filters are suitable for a broad range of applications, including filtration of:

  • Inks and dyes
  • Acids, bases, and oxidants
  • Process water
  • Pharmaceutical preparations
  • Serums and tissue culture media

General Properties

Memtrex MP filters are available the following absolute pore size micron ratings: 0.1, 0.2, 0.45 and 0.65 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 filters may be autoclaved or in situ steam sterilized (up to 257°F [125°C], 30-minute cycles) for a maximum accumulated exposure of 10 hours. Filters which are steam sterilized must have stainless steel insert supported o-ring adaptors. Alternatively, the filters may be sanitized with compatible chemical agents.
  • GE certifies that the material contained in its Memtrex MP pleated filters meet U.S. FDA requirements for food contact under the applicable regulations in 21 CFR. For further information, contact GE technical services. Memtrex MP filters meet the test criteria for USP class VI-121°C Plastics
  • Aqueous extracts from Memtrex MP 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.
