Product Introduction
Hexa Pharma Chem presents the Mixed Cellulose Membrane, manufactured by Beijing Neuronbc Laboratories Co., Ltd. This hydrophilic membrane is composed of cellulose acetate and nitrate, featuring uniform pore size distribution with porosity as high as 80%. The membrane delivers fast flow rates with good interception efficiency, minimal adsorption, and no medium fall-off — all while requiring low working pressure.
With a white and opaque appearance, depth of 100–300 μm, and excellent wettability, these membranes are ideal for solution clarification and sterilization filtration, culture media processing, liquid filter sterilization, air testing of specific pollutants, coliform testing in water, and industrial dust testing. In biological applications, they are widely used for cell collection and cell washing.
