BRPTFE

Summary

Product identification

The BRPTFE-Series are High Purity Bio-Reduction Grade PTFE Filter Cartridges, featuring an expanded polytetrafluoroethylene (PTFE) membrane. These cartridges provide reliable high-LRV reduction of micro-organisms, suitable for bio-process applications where pharmaceutical-grade validation is not required. They offer high-flow, high-capacity membrane filtration with exceptional hydrophobicity.

Key features:

• Reliable bioburden reduction and prevention of process contamination, with proven 7.4 LRV retention of aerosolized bacteriophage.
• Tolerates multiple sterilization cycles by autoclave or in-situ steaming.
• 100% integrity tested in production.
• Manufactured in a clean-room environment.
