Hydrophobic PTFE Membrane Filters / Type 11803

The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.

Item no.:  11803-142------G

Price:  $1,020.00

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 not resistant.
