Parker Tetpor Filter Cartridges

Tetpor Plus Filter Cartridges
Tetpor Plus filter cartridges have been specifically designed for the filtration of liquids and gases in the bulk pharmaceutical, chemical and biopharmaceutical industry where particulate removal, bioburden reduction and guaranteed sterility is required.

The increasing use of ozonation for the treatment of WFI systems has highlighted compatibility issues with vent filters based on standard polypropylene components. The introduction of a fully validated 0.2-micron sterilizing grade TETPOR PLUS filter cartridge provides guaranteed long term performance in these applications with the additional benefit that the water intrusion test method can validate the filters integrity.

The high voids volume single layer PTFE membrane ensures an excellent combination of flow rate and retention.

Features and Benefits
  • Sterile filtration of oxygen / oxygen enriched feeds in cell culture
  • Exceptional resistance to solvents and oxidative environments
  • Ideal for sterile venting on ozonated water systems
  • Fully validated to ASTM F838-83 for sterilizing grade filters
  • PTFE membrane
  • Available in a wide range of micron ratings to suit all applications
