Info

Membrane Filters Membrane filters or membranes are microporous plastic films with specific pore size ratings. Also known as screen, sieve or microporous filters, membranes retain particles or microorganisms larger than their pore size primarily by surface capture. Some particles smaller than the stated pore size may be retained by other mechanisms. Advantec membranes are produced by three different processes. Mixed Cellulose Ester and Cellulose Acetate are reverse phase solvent cast membranes, where controlled evaporation or removal of the complex solvent system forms the porous structure. Both hydrophilic and hydrophobic PTFE are made by a patented process where the membranes are streched biaxially to form the porous structure – PCTE membranes are track etched. Performance characteristics of Advantec membranes • Strong: Advantec membranes are monitered for both burst (longitudinal) and tensile (lateral) strenght. Supported Acetate are the strongest reverse phase membranes available from Advantec. • Chemically and biologically clean: As a part of a comprehensive quality program, only high purity reagents and raw materials are used to produce Advantec membranes. Once cast, the membranes are handled in a class 100 clean room to minimize ambient contamination. While some membranes require a small amount (0,1-3 weight %) of an aqueous wetting agent, Cellulose Acetate has the lowest aqueous extractable (0.1 weight %). All Advantec membranes are Triton- and pyrogen-free (0,005 ng/cm 2 filter area) • Thin membranes with high porosity: Uniformly thin membranes (typically 150 μm) with high porosity (about 80%) provide high gas and liquid flow per unit area. High porosity also provides high surface area for adsorption or binding. • Thermostable: All Advantec membranes can be sterilized by autoclaving. Operation temperatures of up to 180°C can be achieved depending upon the membrane polymer (see individual membrane specifications for details). Advantec membranes exhibit minimal shrinkage at elevated temperatures. 4
