PM 2.5 PTFE membrane filters are designed for PM 2.5 ambient air monitoring. These high-purity, thin filters are sequentially numbered and come with chemically resistant polypropylene support rings.
Applications. Fluorofil™ F100 PTFE membrane cartridges meet the demanding filtration requirements of Pharmaceutical, API and Fine Chemical manufacturers. They can be used for the fine filtration of aggressive chemical solutions including acids, alkalis, solvents and etchants. Carbon fines removal.
Use the information in this table to determine the ability of a specific membrane filter to withstand exposure to a solvent. All concentrations are 100% unless noted. Legend: C = Compatible LC = Limited Compatibility (Membrane may swell and shrink) IC = Incompatible (Not Recommended)
MS ® PTFE membrane media for filtration is made of PTFE (polytetrafluorothylene), and were drawn 2-demension. It is micro-pore film. The PTFE membrane was laminated with great variety of fabric and paper. Applied to extensive industries, including biochemistry, microelectronic, lab material and etc. Directly and indirectly related to pharmacy
2018/8/7 · Membrane-sample Compatibility It’s easy to overlook membrane compatibility when picking out your filter or device for your sample filtration. Good membrane-sample compatibility supports efficient filtration and minimizes resistance, while poor compatibility might result in backpressure, ineffective filtration, or even chemical attack of your membrane, leading to contamination of your filtrate.
What Chemicals are Compatible with PTFE and Teflon®*? PTFE is the most versatile plastic in terms of chemical compatibility. Highly resistant to most acids, alcohols, detergents and solvents. Ideal for use with reactive and corrosive chemicals.

PTFE membranes are naturally hydrophobic, and chemically resistant to all solvents, acids and bases. PTFE membranes do not impart any extractables to the filtrate. PTFE is an ideal membrane for transducer protectors, since it blocks water vapor and is also ideal for filtering and de-gassing chromatography solvents.
3. For having used "sulfonitric acid" (sulfuric and nitric acids mixture) for at least 2 decades, PTFE is definitely stable to such a mixture. Safety on the use of "sulfonitric acid". I know it is off-topic but I think that safety should be learned as light touches, not as a-difficult-to-swallow course.
Chemical Resistance - Zeus fluoropolymers and other engineered products are ideal as transport for today’s highly volatile chemical compounds and exotic fluids. This linear aromatic polymer is semi-crystalline and is widely regarded as the highest performance
Teffil™ and Teffil™ HF are a range of superior pleated PTFE membrane filters with PFA supports. These cartridge filters are suitable for use within a number of microelectronics, process and chemical applications. This chemically inert filter range offers the removal of fine particulate from 0.05-10 micron in challenging operating conditions.
PTFE = Polytetrafluoroethylene including of Teflon®. SS = Stainless Steel (316) PE#1 = Convenional Polyethylene. PE#2 = Rigid Polyethylene. PP = Polypropylene. PVC = Polyvinylchloride. This information, based on experience to date, is believed to be reliable.
2015/7/20 · PTFE is exceptionally sensitive to radiation. PTFE experiences significant damage at lower radiation exposure levels than other polymers. In general, PTFE is considered usable without any significant restrictions only for absorbed doses of up to $100\ \mathrm
