of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols. Pore sizes of 0.2 µm and 0.5 µm are typically used. Sterile venting of vacuum manifolds, fermentation vessels, and filtrate tanks and containers utilize PTFE 0.2 µm membranes.
Foxx Life Sciences. EZFlow 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in 0.22µm or 0.45µm pore sizes. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical.

What membrane filter pore size should I use for sterilization? Regardless of the membrane filter material, always use a 0.2 µm pore size membrane filter as the final filter for any sterilizing filtration. The 0.2 µm membranes used in Thermo Scientific™ Nalgene™ filters have been tested and shown to retain 100% of a challenge of 1 X 107

PTFE membrane and polypropylene housing have broad chemical compatibility. In-line filters can be used to help protect against bloodborne pathogens. They are useful for benchtop fermentors, in-line gas filtration for sterile air or CO2, and protection of vacuum pumps from damage by aqueous solutions.
Hydrophobic membrane filters are typically used with compatible non-aqueous fluids. They are also commonly used as air, gas, or vent filters. Hydrophobic membrane filters are sometimes used with water or aqueous solutions; and, in these applications, they must first be prewet with a low surface tension, water miscible fluid prior to use.
