Hydrophobic sterilizing-grade filters are commonly used as air-vents on processing tanks to maintain near ambient pressure in the tank while ensuring sterility. Tank vent filters remove micro-organisms from the gas as it flows in or out of the tank. MilliporeSigma offers multiple membranes and device formats for vent filtration.
Aervent 0.2 µm hydrophobic polytetrafluoroethylene (PTFE) filters provide sterility assurance, high flow rates and throughput and are used in pharmaceutical applications where it is critical to use a phobic filter with validated bacterial and viral retention capabilities. Available Formats
Hydrophobic Durapore® Filters
Sterilizing-grade Hydrophobic Durapore® 0.22 µm polyvinylidene fluoride (PVDF) membranes for reliable removal of contaminants and microorganisms from gases. Available Formats
Millipore Express® SPG
Sterilizing-grade Millipore Express® SPG filters are gamma stable capsule filters containing 0.2 μm sterilizing-grade membrane. These filters provide optimal gas filtration and venting in single-use applications. Available Formats
Aerex® 0.2 µm PTFE filters are designed for the removal of bacteria and viruses from moist gas streams in non-critical applications. Aerex® filters are not validated for bacterial retention. Available Formats
