An MCE (Mixed Cellulose Ester) membrane filter is a hydrophilic, high-porosity membrane made from a blend of cellulose nitrate and cellulose acetate. It is widely used for microbiological analysis, particulate monitoring, and clarification of aqueous samples. Known for its high microbial recovery, smooth surface, and compatibility with colony growth, the MCE membrane is the gold standard in many regulatory and environmental testing protocols.
