Description
PPTFE-Series High Purity Pharmaceutical Grade PTFE Filter Cartridges, with expanded polytetrafluoroethylene (PTFE) membrane, provide
optimized filtration performance in sterile air/gas filtration and venting applications. The single layer PTFE membrane, with over twice the hydrophobicity of polypropylene or PVDF, is the best choice to prevent water intrusion and resulting microbial growth. Each PPTFE cartridge is integrity tested during manufacturing and is supported by a validation guide for regulatory compliance. PPTFE elements are fully validated as sterilizing grade filters in liquids in accordance with HIMA and ASTM F838-05 guidelines and in gases through full retention of the MS2 phage in an aerosol challenge.
Manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
Typical Applications
• Sterile gas filtration of fermentor inlets
• Off-gassing downstream of fermentors and bioreactors
• Autoclave vent filters
• WFI tank vents
• Sterile air supply for service gases (i.e. filling lines in blow-fill-seal systems)
