PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media
Pall Acro 50 disposable filters are 0.2 micron rated and contain a Pall hydrophobic PTFE membrane and are ideal for the sterile venting of small containers and as an in-line gas filter. The large effective filter area provides high flow rates and filters can be autoclaved several times ensuring low costs.

Sterlitech offers a comprehensive selection of polymeric and inorganic membrane filter materials, enabling users to perform everything from solvent filtration to gas venting. Please consult with our filtration experts for assistance in membrane selection, questions about our products available on a commercial scale, or try a customized sample pack to get started.
Hydrophobic: It’s resistance to water means it never gets wet, making it useful in cooking, wound dressings and more. Chemically inert: The majority of solvents and chemicals will not damage PTFE. Low coefficient of friction: The coefficient of friction of PTFE is one of the lowest of any solid in existence, meaning nothing will stick to it.

Pore Size (0.2 and 0.45 µm) — The filter pore size is usually a personal preference of the chromatographer but relates to the column packing material. Since there are many different packing materials, a general guideline is that most customers find that the 0.45 µm filter meets their requirements, although chromatographers are increasingly moving toward using 0.2 µm filters.

2017/1/8 · PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability. PTFE is hydrophobic and requires pre-wetting prior to use with aqueous solvents. Sterilization: Syringe filters can be sterilized by autoclave at 125° for 15 minutes.
