Membrane filter, PTFE Hydrophobic

The PTFE membrane is made of pure PTFE, laminated to a polypropylene support for improved durability. This membrane is simply the best choice for use with aggressive solvents, liquids, and gases that may attack other media. It is resistant to most acids, alkalis, and solvents. Laminated PTFE filters can also be used to filter aqueous solutions when prewetted with methanol.- compatible with strong acids and aggressive solutions- naturally hydrophobic- improved durability and handling- filtration of strong acids and aggressive solutions- venting applicationsThese filters are compatible with our vacuum filter flasks and

- compatible with strong acids and aggressive solutions
- naturally hydrophobic
- improved durability and handling
- filtration of strong acids and aggressive solutions
- venting applications


These filters are compatible with our vacuum filter flasks and manifold systems however they can be used in many other 3rd party set ups.

High quality membrane disc filters that give consistent and reliable results and are optimised for HPLC media preparation, pharmaceuticals and cold sterilisation.
