Polytetrafluoroethylene (PTFE): Hydrophobic membrane. Resistant to organic solvents as well as strong acids and bases. Low protein binding. Low in extractables. Main applications are the filtration of non-aqueous samples. Prior to filtering of aqueous samples
membrane to the maximum extent possible, the membranes were dried to a freezing state. Before observing the membrane sample, a conductive layer of gold, of approximately 2 nm thickness, was plated on the membrane surface by sputtering (Gatan, USA).1
Membrane filters are available in a wide choice of colors, pore sizes, either gridded or non-gridded, in individually sterile-packaged or non-sterile-packaged versions, and with or without a hydrophobic edge. The Microsart ® e.motion membrane packaging is specially designed for use with the Microsart ® e.motion Dispenser.
PTFE Unlaminated Membrane Filters. 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
PTFE membrane with the 3 times faster flow rate Reducing the scale and cost of a filtration equipment designing With its core character of 3 times faster flow rate than conventional PTFE membrane, the consumption of filter cartridges can be greatly lowered.
The main application of these membrane filters ist the filtration of air, gases and chemicals. 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

2020/7/17 · The retention capacity of the dynamic membrane for fatty acids was 68%, which is 4.6% lower than the retention capacity of the UPM-100 membrane. The obtained hydrophobic dynamic membranes can be effectively used to separate spent emulsions with high specific productivity.
2012/8/13 · PTFE as a Membrane for Syringe Filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or Dissolution Testing. The simple explanation of the differences is that Chemical Resistance is defined as the durability of the membrane to withstand some harsh Solvents (normally not used in HPLC or dissolution testing).
