Memtrex MP-S

Summary

Product identification

The Memtrex MP-S are pleated filters designed for final sterile filtration of biological and pharmaceutical products. They feature a double-layer polyethersulfone (PES) membrane providing low protein-binding, high throughput, and broad chemical compatibility. These filters are available with an absolute pore size micron rating of 0.2 µm.

Typical Applications

Memtrex MP-S filters are specifically designed for sterile filtration of pharmaceutical and biological products. Typical applications include:

• Final Filtration of Drugs and Biologicals
• Final Filtration of Water for Injection
• Final Filtration of Pure Water for Dialysis
• LVPs, SVPs
• Diagnostics
• Tissue Culture Media
• Vaccines

Materials of Construction

• Media: 2 layers of Hydrophilic Polyethersulfone
• Support Layers: Polypropylene Microfiber
• Core and Cage: Polypropylene
• End caps and Adapters: Polypropylene with Stainless Steel Insert

Dimensions

• Nominal O.D.: 2.75” (70 mm)
• Nominal I.D.: 1.25” (31 mm)
• Effective Filtration Area: 6.5 ft² (0.60 m²)

Operating limits

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

Integrity Testing

• Air diffusion per 10" module after saturation with clean water <12 cc/min at 40 psig (2.76 bar).

Flow Performance

The flow performance in clean water is listed in the original document, based on a 10" length filter. See the official PDF for exact tabulated values.

Additional Information

• Memtrex MP-S 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. Compatible chemical agents can also be used for sanitization.
• The materials meet U.S. FDA requirements for food contact under 21 CFR and meet the test criteria for USP class VI-121°C Plastics.
• Aqueous extracts from Memtrex MP-S filters contain less than 0.25 EU/ml, and the filters typically exhibit low levels of non-volatile residues.
• Users should carefully verify chemical compatibility for specific applications.
