PTFE membrane filters are naturally hydrophobic with excellent chemical resistance, making them the ideal choice for sterile venting of gases*, non-aqueous solvents, acids, and aggressive fluids. Thin, highly porous membrane filter. Behaves as an absolute retentive membrane. Inert to most agressive solvents, including strong acids and bases.

Filter units with MS hydrophobic PTFE membrane are ideal for sterilizing gases, venting sterile containers, and sterilizing or clarifying organic solutions and protect your laboratory. The large effective filter area provides high flow rates and filters can be autoclaved several times ensuring low costs.

"The Next Generation of Universal Membrane is here Syringe Filters with wwPTFE membrane for HPLC / UHPLC Sample Preparation • Extend column life up to 52 times • Improve result quality with up to 24% less filter extractables and lower adsorption

7/9/2005 · The PTFE tube is a semipermeable membrane, which allows the permeation of gas inside the system, while the glass sample holder stores the extracted gases. Before use, the device is evacuated, using a syringe, and dipped into water (wells, springs, lakes or rivers).

While LifeStraw Personal is a portable device meant for individual use, LifeStraw Family is aimed at groups of people sharing the water distributed from the filter. Both systems effectively remove 99.99 percent of all bacteria, viruses, and parasites from contaminated water. Also, both can be used as point-of-use treatment filters.

High-purity PTFE membrane filter media provides superior chemical resistance for a broad range of industrial applications. With retention ratings as fine as 0.01μ (10 nanometers), consistent contaminant removal is achieved in aggressive fluids and organic solvents.

Suitable for pressure ranges up to 350 bar. Membrane Filters which protect Gas Analysers from liquids, aerosols and particles. They install in the system tubing or piping directly before the analyser. An Ambient Air Filter with a fine upstream filter which eliminates fugitive particular matter in ambient gas streams.

The sampling device consists of a polytetrafluroethylene (PTFE) tube (waterproof and gas permeable) sealed at one end and connected to a glass sample holder at the other end. The device is pre-evacuated and subsequently dipped in water, where the dissolved gases permeate through the PTFE tube until the pressure inside the system reaches equilibrium.

Hydrophobic PTFE Membrane Filters Highly porous membrance filter. Use to sterilize gasses,vent gas from aqueous solutions,or sterilize or clarify aggressive chemicals. Insert to mostaggressive solvents,strong acids,alcohols,bases,aromatics. Don’t use

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.

Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).
