Membranes – PORAFIL membranes for microfiltration
Membrane filters, PORAFIL CM, Cellulose mixed ester, White
Membrane filters, PORAFIL CM, Cellulose mixed ester, White
Item number: 65100045047
Content: 100piece(s)
PORAFIL CM membranes of cellulose mixed esters are ideal for gravimetric analysis. They are particularly suited for aqueous solutions. The hydrophilic membrane is thermally stable to 125 °C and can be autoclaved at 121 °C. This membrane is often used for contamination tests.

Membrane filters, PORAFIL TE, Polytetrafluoroethylene (PTFE), White
Item number: 670045047
PORAFIL TE membranes of polytetrafluoroethylene (PTFE) are particularly suited for aggressive media, since they are chemically inert towards aqueous and organic solutions as well as towards concentrated acids and bases. These membranes are hydrophobic, thus the pressure for filtration of aqueous solutions has to be higher than the breakthrough pressure. PORAFIL TE membranes can be used at temperatures up to 145 °C.
