Molecular/Por Ultrafiltration Membranes are specifically designed to provide precise molecular separations under the high pressure conditions typically associated with laboratory ultrafiltration. The 2-layer membrane consists of an upper cellulose ester (CE) membrane cast on a porous substructure that provides support to withstand the applied pressure (up to 70 psi/4.8 bar). While the membranous top layer selectively passes the molecular species in solution, the bottom layer does not interfere with the filtration characteristics. Molecular/Por Ultrafiltration Membrane is available in flat-sheets and 3 disc sizes with precise MWCO's ranging from 100 D -100 kD.
