Memtrex MP-S

Summary

Product identification

The Memtrex* MP-S Pleated Filters are 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.

• Absolute Pore Size Micron Rating: 0.2 µm
• Typical Applications:
  • 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

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
• Sterilization/Sanitization:
  • May be autoclaved or in situ steam sterilized up to 257°F (125°C) for 30-minute cycles, with a maximum accumulated exposure of 10 hours.
  • Alternatively, filters may be sanitized with compatible chemical agents.

Mechanical / Hydraulic

• Dimensions:
  • Nominal O.D.: 2.75” (70 mm)
  • Nominal I.D.: 1.25” (31 mm)
  • Effective Filtration Area: 6.5 ft² (0.60 m²)
• Integrity Testing: Air diffusion per 10" module after saturation with clean water <12 cc/min at 40 psig (2.76 bar).
• Flow Performance in Clean Water: See the official PDF for exact tabulated values. (Data based on 10” length filter.)

Compliance and Certifications

• Meets U.S. FDA requirements for food contact under applicable regulations in 21 CFR.
• Meets test criteria for USP class VI-121°C Plastics.
• Aqueous extracts from filters contain less than 0.25 EU/ml.
• Filters typically exhibit low levels of non-volatile residues.
• Designed and manufactured for resistance to a wide range of chemical solutions; users should verify chemical compatibility for their specific application.

Ordering Information

The ordering code follows the format MMP-S (Type) ## (Micron Rating) - (Length) - (End #1 Adapter) - (End #2 Adapter) - (Elastomer) - (Grade).

• Type: MMP-S
• Absolute Micron Rating: 92 = 0.2 μm
• Nominal Cartridge Length:
  • 1 = 10 inch (25 cm)
  • 2 = 20 inch (51 cm)
  • 3 = 30 inch (76 cm)
  • 4 = 40 inch (102 cm)
• End #1 Adapter:
  • Q = 222 O-Ring Stainless Steel Support Ring
  • Z = 226 O-Ring Stainless Steel Support Ring
  • A = Open End Gasket
  • B = 120 O-Ring
  • C = 213 O-Ring
  • G = Closed End Cap
  • H = Fin Adapter
• Elastomer Material: S = Silicone
• Grade: S = Sterilizing
