1.2 Um Polytetrafluorethylene Membrane By Sartorius

MEMBRANE FILTER, PTFE, PORE 1.2UM, D 100MM
25/PK
Hydrophobic PTFE The main application of these membrane filters is the filtration of air, gases or chemicals They are made of PTFE (polytetra-fluorethylene) only and are therefore permanently hydrophobic Unlike other (hydrophilic) filter types, they are not wetted by air humidity, allowing unhindered passage of air at low differential pressures as well 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 Due to their hydrophobic characteristics, they must be pre-wetted with ethanol or methanolbefore the filtration of aqueous media
