Sartorius membrane filter, grade 11806, PTFE, hydrophobic, pore size 0.45 µm, diameter 13 mm

The main applications of these membrane filters are filtration in the air and gases and filtration of chemicals. PTFE membrane filters have excellent chemical resistance (pH 1-14), so they are also used for filtration of solvents and acids, to which other types of fitters are unresistant.
