mixed cellulose ester(MCE) membrane filter and cellulose acetate membrane filter are ideal for Colony Counting and Sterility Testing. MS sterile gridded MCE membrane filter is unsupported, naturally hydrophilic membrane. MS® MCE membrane filter are composed of cellulose acetate and cellulose nitrate, which has made it one of the most widely used membranes in analytical and research applications. MS® Cellulose acetate(CA) membrane filters are composed of pure cellulose and its very low protein binding capacity makes it ideal for protein filtrations, tissue culture media sterilization, and biological fluid filtration
