Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes. WTP and TE membrane ranges:
Sigma Aldrich ptfe membrane for air Methanol | CH3OH - PubChem Methanol | CH3OH or CH4O | CID 887 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety
single-use, disposable filters remove particles larger than the membrane’s rated pore size and are recommended for filtering 10–100 milliliter (mL) volumes to remove particles prior to instrumentation analysis. The Millex® syringe filter consists of a membrane and/or glass fiber filter in a high density polyethylene housing.
Apr 03, 2019 · Benefits of PTFE-based filtration materials for cleanroom HVACs. High efficiency combined with a low-pressure drop is a feature of PTFE filter media and here, 99.99999% of filtration efficiency with ULPA grade PTFE stretched film is possible. The pressure drop will increase at this extreme level of filtration, but the PTFE material still
Mitex™ PTFE Membrane is unaffected by almost all liquids, including organic solvents, concentrated acids and bases, propellants, and cryogenic fluids. Mitex™ membrane is unbacked, yet is easy to handle, combining the convenience of a backed membrane with the versatility of a pure PTFE membrane. Mitex™ membrane is hydrophobic.

Inherently hydrophobic, PTFE membranes will not absorb moisture from air or gases, making it ideal for venting applications, phase separations and aerosol samplings. Laminated PTFE filters can be used to filter aqueous solutions when prewetted with methanol. They are autoclavable up to 130°C.
Oct 10, 2011 · Classic Filters first introduced PTFE membranes in 2002. They are most commonly used in sample systems to protect expensive and sensitive analytical equipment. Because they are hydrophobic water is repelled from the surface and pores of the membrane and cannot pass through. The newly introduced oleophobic membranes add a new dimension to the
Difference from glass fiber membrane, the PTFE filter is a kind of membrane material for deep filtration. The membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene. No additives in the whole process; stable physical and chemical properties and good compatibility.
