PVDF Membranes. Polyvinylidene difluoride (PVDF) membrane filters are mechanically strong, exhibit superior chemical resistance, and high thermal stability. Available in both hydrophilic and hydrophobic options. We provide the filters and technical support to help you take your breakthrough product from an idea to a prototype, to commercial scale.
The 0.5 μm pore size is normally used. 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.

Jun 30, 2012 · Aliquots of dissolution media were sampled and filtered through 0.2 μm GHP filters. In all cases, the filtrate was completely clear upon visual inspection. Filtered aliquots were then diluted in a 1:1 ratio with acetonitrile, vortexed for 3 min and centrifuged (Microfuge 18 Centrifuge, Beckman, Fullerton, CA) at 3,000 rpm for 15 min.
Jul 09, 2019 · The membrane is hydrophobic in nature. It has good chemical resistance, which makes it very suitable for filtering solvents or other corrosive chemicals that other membranes cannot filter. Main uses: Hydrophobic PTFE membrane filter can be used for atmospheric filtration detection, usually only for air filtration. Uncommon hydrophobic membranes can also be used to filter certain organic solvents, such as ethanol.
