Nest Scientific mixed cellulose ester (MCE) filtration membranes are made from a blend of biologically inert cellulose nitrate and cellulose acetate polymers. Their consistent microporous design ensures exceptionally fast flow rates and high filtration capacity, making them among the most efficient membrane filters available.

Due to their inert nature, MCE membranes can be used for a wide range of applications such as microbiological testing, solution clarification, sterilization, industrial hygiene assessments, particulate matter analysis, and silt density index evaluations.
