Graver Technologies, LLC announces the release of the TefTEC™ P Series filter cartridge which features a liquid sterilizing grade e-PTFE membrane with polypropylene structural components.

TefTEC P filter cartridges have been documented for completed microbial removal when challenged at a level of 107 /cm2 in liquid, which is the more stringent microbial retention requirement. Each lot of cartridges is further qualified with microbial challenge testing to verify performance Additionally, the TefTEC P has been challenged with ØX174 bacteriophage to demonstrate the removal of aerosolized viruses. TefTEC P cartridges are produced and manufactured in an ISO cleanroom and are 100% integrity tested prior to release to ensure performance standards. A Validation Guide is available to support the product claims.
