The Continuous Packed MCE Gridded Membrane is a mixed cellulose ester (MCE) membrane filter commonly used in microbiological testing, especially for water, food, and pharmaceutical samples. It features a hydrophilic surface, high porosity, and a pre-printed grid, which enhances colony counting accuracy. “Continuous packed” refers to the packaging format, where membranes are packed in a stack (often without individual wrappers) for automated or high-throughput manual use.
