PharmaDoer® PTFE-HT Series Sterilizing Grade PTFE Pleated Filter Cartridges for air & gases. Increased temperature tolerance
PharmaDoer PTFE-HT series polytetrafluoroethylene (PTFE) pleated filter cartridges provide effective removal of microbes and submicronic particulate. Using inherently hydrophobic PTFE membrane, the PharmaDoer-PTFE-HT series has been designed specifically for feed air and venting in fermentation processes to prevent system contamination. Oxidation-resistent polypropylene hardware and polyester media support provides an extended operating temperature range.
Delivers fully retentive performance of aerosolized bacteriophage. Also is ideal for filtration of bulk gases and compressed air. Cartridges receive an ultra-pure water rinse to attain a low degree of extractable substances.
Features
