PTFE membrane filters are naturally hydrophobic with excellent chemical resistance, making them the ideal choice for sterile venting of gases*, non-aqueous solvents, acids, and aggressive fluids. Thin, highly porous membrane filter. Behaves as an absolute retentive membrane. Inert to most agressive solvents, including strong acids and bases.

2020/10/13 · Our new hydrophobic and oleophobic polyethersulfone membranes are designed for fast air filtration or sterile venting while preventing any liquid passage or condensate blockage. Their high performance and superior gamma stability make them a very efficient and powerful alternative to PTFE and will help you to increase your process and product
25mm<100ml. Maximum Opearting Temperature : 130℃. Maximum Opearting Pressure (psi) : 87psi. PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases. Very resistant to solvents as well as acids or bases. Can be made more hydrophilic by flushing with alcohol, followed by water.
PTFE membranes are hydrophobic; thus they are ideal for the filtration of nonpolar liquids and gases. They arevery resistant towards all kinds of solvents as well aswith acids or bases. By flushing with alcohol, followed by water, the originally hydrophobic membrane can bemade more hydrophilic. Related Products: 0.45 Ptfe Filter Compare this item
2022/10/24 · Hydrophobic membrane filter prevents moisture from passing through air vents and is resistant to almost all chemicals. Hydrophobic PTFE membrane filters have round disc types and roll types are both available for different applications. The operating temperature ranges from -120°C to 260°C. Inert to most aggressive solvents, including strong acids.
Hydrophilic PTFE Membrane Nexpore hydrophilic PTFE membrane is made of pure PTFE membrane bonded to a polypropylene non-woven support. The extreme chemical compatibility (pH 1-14) makes it an ideal material for filtration of almost all solvent, acids and alkaline solutions, and organic-based aqueous samples, and is commonly used for HPLC solvents sample preparation.
2019/07/09 · Features and advantages of PTFE hydrophilic or hydrophobic membrane filter 1. No fiber, no leachable problem 2. High durability and fast filtering speed 3. High temperature resistant and sterilizable 4. Low background value, accurate test results 5. Resistance to strong acids, strong alkalis, and corrosive solutions 6.
Specifications Order information Hydrophilic PTFE membrane is optimized for low drug and protein binding with excellent throughput in typical aqueous and solvent sample preparation. High sample recoveries and low extractables provide for optimum analysis by HPLC and LC/MS/MS.

Our unsupported, hydrophobic, PTFE membrane filters are ideal for sterilization and venting applications involving air, gasses, and solvents/acids incompatible with most other filters. These PTFE filters are chemically and biologically inert, stable up to 260°C, and will withstand the majority of concentrated acids and bases and are especially useful for environments that contain water
2022/11/24 · Hydrophilic PTFE membrane filter Features: relatively uniform pore size, high porosity, no media shedding, thin texture, low resistance, fast filtration speed, and very little adsorption. The Hydrophilic membrane is able to filter strong corrosive chemicals in almost all organic solvents, whose performance is just the opposite of that of the hydrophilic membrane.
