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.

Glass fiber filters are produced from borosilicate glass fibers and are typically used for pre-filtration. Membrane Pore Size. 0.45 µm membranes are used for clarification and particulate removal; 0.20 µm and 0.22 µm membranes can be used for filter sterilization and ultracleaning of aqueous solutions and organic solvents for HPLC

recommended as an excellent general purpose/high-performance sample filter for most applications. Ptfe Polytetrafluoroethylene(PTFE) - Phenex-PTFE membranes are inherently hydrophobic and excellent for filtration of 100 % organic or highly acidic or basic samples. Pes Polyethersulfone(PES) - Polyethersulfone membranes exhibit very

Pall’s sterile syringe filters are available with a variety of high-performance membranes to suit application requirements: Fluorodyne® II Membrane - For high flow rates and low protein binding. Not recommended for use with some ethers. Supor® Membrane - For high throughputs, fast filtration, and low protein binding.

Shelco Filters' MicroVantage™ membrane filter cartridges are the premier choice when high purity and absolute retention are prerequisites for the filtration process. These premium performance cartridges are available with Polyethersulfone, Polysulfone, Nylon 6,6 and PTFE membranes and designed with the maximum surface area to optimize service

Due to its strength and broad chemical compatibility, PTFE is commonly used in membrane filters. While PTFE is known for its high strength, the addition of a high-density polyethylene (HDPE) backing offers improved filter handling characteristics. Hydrophilic LCR and Omnipore™ PTFE membranes are typically used for filtering aqueous solutions.

The family of LiquiPro™ F2, F3 and SH filters come with Hydrophobic PTFE membrane and PFA core, cage, endcap hardware that will meet all requirements. In etching or stripping processes where less aggressive chemicals are used, the Fluoropolymer membrane with Polypropylene hardware would be applicable.

PTFE Membrane Housings. PTFE-membrane housings with both hydrophobic and oleophobic membrane types for high-performance separation liquid from gases. Combination housings with both a PTFE-membrane and coalescing filter element. Liquid/liquid separation is also possible using our specially designed membrane housings. More

Helapet CO 2 incubator disc filters fit directly on to any standard desktop CO 2 incubator to resist substances from entering the chamber. Each standard CO 2 incubator disc filter is available using a high-performance PTFE membrane which filters particulates to prevent contamination, whilst resisting moisture and ensuring excellent flow rates.

Feb 17, 2020 · With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.

PTFE (Polytetrafluoroethylene) Membrane Filters. 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.

The hydrophobic characteristics of the ePTFE membrane makes the Fluorofil™ filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed. For solvent and aggressive chemical filtration applications, Fluorofil™ cartridges offer a wide range of chemical compatibility with high thermal stability.

It is important to choose a filtration membrane that has high chemical compatibility with the mobile phase solvents used in the lab. Polytetrafluoroethylene (PTFE), polyvinylidene difluoride (PVDF), and regenerated cellulose (RC) membranes are popular choices, because they are highly compatible with common mobile phase solvents such as purified

Description. Pall Mini Kleenpak capsules with Emflon ® PFR media are designed for air filtration and vent applications where the use of a filter of small size and low weight is critical. Having a surface area of 280 cm², each Mini Kleenpak capsule filter contains a proprietary high performance PTFE membrane which is inherently hydrophobic and
