Microfluor II Cartridge and Capsule Filter Applications
Microfluor II filters are optimized for applications requiring sterilization of air, gas, or aggressive solvents and chemicals. The hydrophobic PTFE filter membrane prevents wetting with aqueous liquids or moisture that can block free air flow. Some applications, however, may require filtration of aggressive fluids such as acids or bases. Depending on compatibility, Microfluor II filters can be used to provide sterile filtration of these fluids by prewetting the membrane with a low surface tension fluid such as alcohol.

A list of Microfluor II filter applications includes:
Sterile venting of process tanks
Sterile filtration of process air and aseptic filling lines
Sterile venting of lyophilizers
Sterile venting of autoclaves
Sterile air filtration on blow, fill, and seal machines
Sterilizing filtration of fermentation inlet and exhaust air
Sterile filtration of aggressive liquids

Microfluor II filters have been designed to provide exceptionally high flow rates with low differential pressures. Microfluor II filters are available in a range of cartridge and capsule filter configurations to meet any process requirement.
