PTFE membrane filter is used to sterilize gasses, vent gas from aqueous solutions, or sterilize or clarify aggressive chemicals. Widely used in the fields of pharmacy, food processing, biochemistry, microelectronics, and laboratory consumables. Purify samples and mobile phases of HPLC and GC. Solvent sterilization.

Clean Gas Filter: Cartridge Type/Disc Style Series SFA100/200/300 Precision filtration for general gases used in the electronic industry, etc. Compressed air, Nitrogen, etc. PTFE membrane element is made into a cartridge. Made into a cartridge by polyester holder and fluorine rubber (FKM) gasket. All products are tested at the time of shipment.

Filter Membrane Types. Reinforced cellulose membranes (RW filters) are rigid screen filters.Their rigidity, high-capacity, and low pressure drop make RW filters ideal for the removal of contaminants from heavily contaminated liquids and gasses, particularly for prefiltration.

MS® PTFE Venting Membrane Applied in Gas Sensors . DESCRIPTION. Gas sensors not only have high requirements for IP rating, but also have high requirements for air perm to accurately detect the content of some specific gas in the air. Then gas sensors have very high requirements for air perm stability of the membranes.

DESCRIPTION. Membrane solutions offers a range of various PTFE hydrophobic membrane applied for air filtration . Material characteristics of the PTFE hydrophobic membrane include high flow rate and long service life at low operating pressures,so they are ideal for sterile filtration and venting of air/gases.

PTFE filters are the versatile choice for size-selective samplers. The material’s unique properties make it ideal for gravimetric, chemical, and/or microscopic analysis of sample particulate. PTFE filters are used for aerosol sampling, air venting and gas filtration. Note that the back pressure on PTFE filters can vary within the same lot.

0.2 Micron Filters. The 0.2 micron filters are an extremely popular pore size due to the wide range of industries they serve. Because it is such a vital pore size, the 0.2 micron filters come in a wide variety of filter types and configurations to serve all industries.

Hydrophobic membrane filters are typically used with compatible non-aqueous fluids. They are also commonly used as air, gas, or vent filters. Hydrophobic membrane filters are sometimes used with water or aqueous solutions; and, in these applications, they must first be prewet with a low surface tension, water miscible fluid prior to use.

PTFE membrane is a thin, highly porous film that behaves as an absolute retentive membrane. Their inherently hydrophobic nature make PTFE membranes ideal for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or sterile venting fermentation tanks. PTFE is inert.

Medical Millex-GP Syringe Filter Unit, 0.22 µm, polyethersulfone, 33 mm, sterilized by gamma irradiation. A 33 mm diameter sterile syringe filter with a 0.22 µm pore size hydrophilic Polyethersulfone (PES) membrane. Comes in a pack of 50. A 25 mm diameter sterile syringe filter with a 0.22 µm pore size Polyethersulfone membrane.

Mitex™ membrane filters are PTFE without a backing material and are unaffected by many liquids. These membranes are hydrophobic and can only be used with gases or non-aqueous fluids unless they are prewet with low-surface-tension fluid such as methanol.

Air and gas sterilization* make use of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols. Pore sizes of 0.2 µm and 0.5 µm are typically used. Sterile* venting of vacuum manifolds, fermentation vessels, and filtrate tanks and containers utilize PTFE 0.2 µm membranes.

Catalog number: DS0222-0045. Nalgene™ 50mm inline filter with PTFE membrane provides an excellent barrier for sterile venting of benchtop fermentors, in-line gas filtration, or protecting vacuum pumps from moisture. It also gives the ability to filter aggressive chemicals, including acids and non-aqueous solvents, such as those used in GC and

Emflon® PFR Membrane Filter Cartridges offer high assurance and high integrity in their air and gas sterilizing services. Filters can be steamed and tested easily to maintain cleanliness and integrity standards. Keeping filters clean and up to date provides a long service life for the user.
