Hydrophilic PTFE membrane is wettable. It can offer superior chemical compatibility, resistant to almost all kinds of solvents. It’s applicable for organic solvents filtration, acids or bases filtration, strong oxidizing solutions, etc. Features and Benefits Superior
S series (Organic solvents) S series are installed Teflon filter (polytetrafluoroethylene, PTFE) with strong resistance to organic solvents, acids and alkalis. They are best suited for prefiltration of samples with aggressive organic solvents such as chloroform and tetrahydrofuran.
PTFE. Polytetrafluoroethylene (PTFE) is a highly hydrophobic fluoropolymer. Filter membranes made using this material are ideal for filtering non-aqueous chemicals and solvents, purifying process air and gases, and protecting tank contents via tank vent filtration. Available pre-wetted for use in aqueous applications. Explore All Filter Products.
Semiconductor Filtration & Purification Products. Increasing semiconductor process challenges rely on water, chemicals, solvents, and gases which are free of yield killing submicron or nanometer size particles, as well as metal, ionic, and organic contaminants which can be leached from wetted materials. Filtration of these fluids is a critical
accordance with iso 9001. * Both types of PTFE, hydrophobic and hydrophilic, have the same colour. Q-Max® RR PTFE/L Hydrophilic PtFe membrane with solvent, base and acid resistance like the hydrophobic type, but also suitable for filtration of aqueous ...
PTFE Filter Cartridges are designed for the majority of pharmaceutical liquids, but especially for solvent-contain-ing liquids and ophthalmic solutions. These ˜lters are composed of a hydrophilic PTFE membrane which provides excellent chemical and heat tolerance.
Useful for alcohols, cryoprotectants such as DMSO and with aqueous/biological and weak solvents. Polypropylene housings with pink color rings. PTFE. Naturally hydrophobic. Excellent for HPLC/GC solvent filtration. Ideal for sterile venting of air or other gases during filtration. Polypropylene housings with white color rings.
solvent/ chemical resistance. Polytetrafluoroethylene (PTFE) Membrane Considerations: Polytetrafluoroethylene membrane is hydrophobic and will not allow water to pass without high pressures. Aqueous solutions may be filtered if the membrane is initially
Proflow II-G filter cartridges provide an economic alternative for general applications where reliable gas and liquid flow rates are required. With 5.6 square feet of expanded PTFE membrane, Proflow II-G filter is a highly efficient hydrophobic barrier, for the production
