Broad range of ultrafilter membrane discs for sample concentration in stirred cells. Membranes made of PES, cellulose triacetate or Hydrosart® regenerated cellulose. Available with various MWCO’s and diameters.

The Polyethersulfone (PES) membrane is a general purpose membrane that provides excellent performance with most solutions when retentate recovery is of primary importance. PES membranes exhibit no hydrophobic or hydrophilic interactions and are usually preferred for their low fouling characteristics, exceptional flux and broad pH range.
