GVWP04700. Trade Name. Durapore ®. Description. Durapore® Membrane Filter, 0.22 µm. Background Information. Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes. Features & Benefits.
Non-Sterile Mixed Cellulose Esters Membrane Filters - White, 0.45µm. Advantec MFS. Esters (MCE) membrane is a general purpose filter used in many applications for the microbiological examination of water, wastewater, pharmaceuticals, food, and beverages, and air monitoring. MCE membranes offer high recovery rates and superior flow rates.
This product was manufactured with a PTFE membrane which meets the criteria for a "non-fiber releasing" filter as defined in 21 CFR 210.3 (b) (6). Virus Aerosol Retention Rated for aerosol retention of a total challenge of 108–1010 plaque forming units of ΦX-174 virus particles at 85 Nm3/h (50 SCFM) per cartridge.
2018/11/14 · After the PTFE hollow fiber membranes were applied for air filtration, several physical methods were used to clean the fouled membranes, including air back purge, water backwash, and water rinsing. To examine the efficacy of these physical methods, the flow of fresh air was compared with that produced by the new module at the same dead-end pressure.
Aervent cartridges have a 0.2µ PTFE membrane and are used in pharmaceutical applications where it is critical to use a phobic filter that has proven bacterial and viral retention capabilities. Common applications for Aervent are fermentation air applications, bioreactor inlet and outlet filtration and sterile process gases.
This product was manufactured with a PTFE membrane which meets the criteria for a "non-fiber releasing" filter as defined in 21 CFR 210.3 (b) (6). USP Bacterial Endotoxins A sample aqueous extraction contains less than 0.5 EU/mL as determined by the Limulus Amebocyte Lysate (LAL) test.
The PTFE membrane can be classified based on the mechanism as, the membrane that gets wet with water and the membrane that gets wet with low surface tension liquids. Both the types of PTFE membranes offer filtration of air, gases and fluids as the primary application, since the PTFE membrane is biologically and chemically inert and is a stable material.
7.5.1 Ptfe Filters are Widely Used in Air and Gas Filtration Table 53 Polytetrafluoroethylene Membrane Filters Market, by Region, 2016-2019 (USD Million) Table 54 Polytetrafluoroethylene Membrane Filters Market, by Region, 2020-2025 (USD Million)
Membrane filters, produced by precipitation or stretching of polymeric materials, are used for a variety of applications (e.g. filtration, air particle monitoring). Properties of membranes differ markedly based upon their composition, fabrication method, surface treatment
PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of
