PTFE membrane filters providing the utmost assurance of chemical resistance, durability and critical filtration performance in aggressive fluids. Ultradyne ® absolute-rated polytetrafluoroethylene (PTFE) membrane filters offer the highest level of assurance of chemical compatibility and filtration performance in aggressive chemicals, prolonged hot air service and other severe process conditions.
The Chemflow®-PE SELECT filter cartridge uses a PTFE membrane along with HDPE supports that provide an economical high-performance alternative to all-fluoropolymer cartridges. The Chemflow®-PE SELECT provides a high degree of retention and cleanliness.
2020/5/1 · The optimal Teflon/PE membrane has high permeances of 4–8 L/m 2-h-bar for hydrophobic solvents such as toluene and hexane but almost no permeance for polar solvents like methanol, DMF and DMSO. 4. The optimal Teflon/PE membrane is stable for the separation of an acetone/RB mixture for 400 h by means of a cross-flow set up.
PTFE membrane filters are strong and resistant to acids, bases, and solvents, and stable at high temperatures. With their low background and low tare mass they are ideal for gravimetric or aerosol/gas/vapour sampling. They are also available in preloaded, leak
2005/10/4 · The latter was used to prepare Nafion solutions with specified solvents. A porous polytetrafluoroethylene membrane (PTFE membrane, Yue-Ming-Tai Chemical Ind. Co., Taichung, Taiwan) with a thickness of 18 ± 3 μm, pore sizes of 0.5 ± 0.1 μm, and a porosity of
Fine or coarse particulate removal from solvents. Designed for fine and sterile filtration steps in food, beverage, pharmaceutical & high purity applications. Polished and hygienic 316L stainless steel construction. Suitable for code 7 style single & multi-cartridges in a range of connection sizes and types.
2020/11/18 · Prior to the test, the membrane was placed in the cell and compacted with both pure water and methanol for 1 h, respectively, to wash away any possible unreacted monomers and make the membrane
Polytetrafluoroethylene (PTFE) Membrane. GVS Laminated PTFE filters are made of a polytetrafluoroethylene polymer (PTFE) laminated to a polypropylene support for improved durability and easy handling. These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols. PTFE
Membrane Solution’s advanced PTFE membranes (pore size:0.03-5μm) achieve the perfect combination of high flow rate,high retention and cost-effective. Material characteristics of MS®PTFE membrane include small diffusion flow and more pores in any given area. MS®PTFE membrane for filtration including hydrophobic membrane and hydrophilic
PFA combines many of the properties of PTFE and FEP. PFA tube is often used when clarity, flexibility, and a higher continuous operating temperature range are required. PFA tubing can be used with all industrial solvents, chemicals, and corrosive materials even
Organic solvent filtration does need special membrane materials suitable for such processes. We from Novamem not only can help you selecting the right solvent filtration material. Upon your request, we can even offer custom manufacturing also for your application.
Filter both aqueous and organic solvents Optically clear when wet Hydrophilic PTFE membranes are a thin, unsupported, highly porous film that offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents. This membrane exhibits high flow rates with minimal
Millipore ® membranes have supported laboratory filtration in academic, pharmaceutical, and industrial sectors since the 1950s. We provide a range of membrane chemistries including MF-Millipore ® mixed cellulose esters, Durapore ® PVDF, Millipore Express ® PLUS polyethersulfone, as well as hydrophilic and hydrophobic PTFE.
Phase change solvents represent a new class of CO2 absorbents with a promising potential to reduce the energy penalty associated with CO2 capture. However, their high volatility is a major concern for their use at the industrial scale. It is believed that membrane absorption offers a solution to overcome this issue, particularly if the membrane can prevent amine evaporation. In the present
Description: This thin, highly porous PTFE membrane is inert to most chemically aggressive solvents, strong acids, and bases that may be incompatible with supported PTFE filters. Ideal for sterilizing gases because it will trap aqueous aerosols on the surface.
