Sartorius Polytetrafluorethylene (PTFE) Membrane Filters

The main application of this membrane filter types is the air/gas-filtration. They are made purely of PTFE and are therefor permanentely hydrophobic. Unlike other (hydrophilic) filter types, they are not wetted by air humidity. PTFE membrane filter have an excellent chemical compatibility, so that they are also used for the filtration of solvents and acids, to which other filters are not resistent. Due to their hydrophobic characteristics, they must be prewetted with ethanol or methanol before the filtration of aqueous media.
