Munktell polyethersulfone membrane filters



Polyethersulfone membrane filters offer the user high flow rates with low adsorption. Particularly suitable for biological and pharmaceutical analytics. The mechanical stability is higher than with cellulose-type membranes. They are an appropriate medium for aqueous and organic solutions in a pH range of 2 - 12.
