Memtrex MP-E

Summary

Product Identification

Memtrex MP-E (MMP-E) filters incorporate a modified asymmetric polyethersulfone membrane with a polypropylene support layer and components, designed for enhanced service life and cleanliness in UPDI water and other microelectronics applications. These Electronics (E) Grade filters undergo a high-purity rinse to reduce TOC and trace metals below 5.0 ppb, making them ideal for final filtration on DI water pads and Point of Use (POU) applications. They are 100% integrity-tested to ensure reliable particle retention.

Typical applications include:

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

Memtrex MP-E filters are available with the following absolute pore size micron ratings: 0.03, 0.1, and 0.2 µm.

Materials of Construction

• Media: Hydrophilic polyethersulfone membrane
• Support Layers: Polypropylene Microfiber
• Core and Cage: Polypropylene
• Endcaps & Adapters: Polypropylene

Mechanical / Hydraulic

• Nominal O.D.: 2.75” (70 mm)
• Nominal I.D.: 1.25” (31 mm)
• Effective Filtration Area: 8.1 ft² (0.75 m²)

Operating Limits

• Maximum Forward Differential Pressure: 60 psi (4.1 bar) at 70ºF (21ºC)
• Maximum Reverse Differential Pressure: 30 psi (2.1 bar) at 70ºF (21ºC)
• Maximum Operating Temperature: 180ºF (82ºC) at 10 psid (0.7 bar) in water

Integrity Testing

(Air diffusion per 10" module after saturation with clean water.)

• 0.03 µm Pore Size Rating: ≤45 cc/min at 50 psig (3.45 bar)
• 0.1 µm Pore Size Rating: ≤45 cc/min at 50 psig (3.45 bar)
• 0.2 µm Pore Size Rating: ≤19 cc/min at 30 psig (2.1 bar)

Additional Information

• Memtrex MP-E filters with polypropylene components can 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. Filters with polyethylene components must not be autoclaved or steam sterilized. They may alternatively be sanitized with compatible chemical agents.
• The 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.
• Memtrex MP-E filters meet the test criteria for USP Class VI-121°C Plastics and pass the MEM Elution Cytotoxicity Test.
• Aqueous extracts from Memtrex MP-E filters contain less than 0.25 EU/ml and typically exhibit low levels of non-volatile residues.
• Filters rinse to less than 5 ppb TOC and less than 5 ppb trace metals in 25 minutes at 2.5 gpm per 10" module in UPDI water.

Flow Performance

Data for flow performance in clean water is based on a 10" length filter. See the official PDF for exact tabulated values.
