Memtrex MP-E

Summary

Product Identification

Memtrex MP-E (MMP-E) filters are pleated filters incorporating a modified asymmetric polyethersulfone membrane with polypropylene support layer and components. They are designed for enhanced service life and cleanliness in ultrapure deionized (UPDI) water and other microelectronics applications.

The Electronics (E) Grade Memtrex-MP-E filters undergo a high-purity rinse to reduce TOC and trace metals below 5.0 ppb. They are 100% integrity-tested to ensure reliable particle retention.

Available absolute pore size micron ratings:

• 0.03 µm
• 0.1 µm
• 0.2 µm

Typical Applications

Memtrex-MP-E filters are specifically designed for the filtration of ultrapure semiconductor water. Typical applications include:

• UPDI Water Pad
• High Purity Chemicals
• Point of Use Applications

Product Water

• TOC and trace metals reduced below 5.0 ppb (for E-Grade).
• Aqueous extracts from Memtrex-MP-E filters contain less than 0.25 EU/ml.
• 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.

Sterilization and Compliance

• Sterilization:
  • Memtrex-MP-E filters with polypropylene components may be autoclaved (121°C, 30 minute cycles) or in situ steam sterilized (125°C, 30 minute cycles) for a maximum accumulated exposure of 10 hours.
  • Memtrex-MP-E filters with polyethylene components must not be autoclaved or in situ steam sterilized.
  • Alternatively, filters may be sanitized with compatible chemical agents.
• Compliance:
  • Component materials are suitable for use in articles intended for repeated food contact as specified in the United States Code of Federal Regulations, Title 21.
  • Meet the test criteria for USP class VI-121°C Plastics.
  • Pass the MEM Elution Cytotoxicity Test.
