2018/8/7 · DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO. MAYBE USE: when you need to filter aqueous solutions and sodium hydroxide. You’ll need to pre-wet with a water-miscible solvent, such as methanol, to overcome the hydrophobicity of the membrane.
SiliCycle Syringe Filter Polytetrafluoroethylene (PTFE) Hydrophobic polytetrafluoroethylene syringe filter is an excellent media for filtration of strong acids and aggressive organic solvents. Wetting the membrane with alcohol and water gives a hydrophilic characteristic.
VWR International – Filter papers - a guide www.vwr.com VWR International – Filter papers - a guide 3 Quantitative filter papers – ashless grades (Ash 0.007%) Grade 40: 8 μm The classic general purpose ashless filter paper with medium speed and retention.
Fluorofil™ ePTFE Membrane Cartridge Filters. Fluorofil™ cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials. Fluorofil™ cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics
Industrial products developed with Teflon™ fluoropolymers gain exceptional resistance to high temperatures, chemical reaction, corrosion, and stress cracking. The properties of Teflon™ products make them the preferred solution for a host of industrial and consumer applications, as well as diverse processing techniques.
is 0.03%. It resists most strong mineral acids and bases, but, like the other polyole˚ns, it is subject to attack by oxidizing agents. For more information visit our website: www.hmcpolymers.com HMC PP resins are appreciably affected by chlorosulfonic acid and
PTFE extruded tubing, and PTFE shrink tubing, are used by our customers in various industries and in different applications, which may require resistance to specific chemicals. While this chart is a useful reference, please note that it is the end users' responsibilities to evaluate and test the fitness of the product for their specific applications.
The Transwell-COL insert contains a PTFE membrane that has been treated with an equimolar mixture of types I and III bovine placental collagens. This results in a biologically stabilized collagen matrix covering the fibrils of the filter membrane. These Transwell
Fiberglass has excellent resistance to most acids, but is attacked by hydrofluoric acid. Not recommended where bases and salts such as chlorides, bromides, and cyanides are present. This media has poor flex abrasion qualities and requires a 20 vertical wire minimum support cage when used in tubular bag form.
Pierce PVDF Transfer Membrane, 0.45 µm, is made of high-quality polyvinylidene difluoride and provides high binding capacity for proteins and nucleic acids for western, southern, and northern blotting methods. The 0.45-µm pore size makes this membrane ideal for transfer for

2017/1/8 · Polytetrafluoroethylene (PTFE) PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability. PTFE is hydrophobic and requires pre-wetting prior to use with aqueous solvents.
binding with the membrane or introduce unexpected interferences to the samples from the syringe filter. Therefore, low protein binding and cleanliness are important features of a syringe filter’s performance. Polyethersulfone (PES) and polyvinylidene
