Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose filters. MCE is easier to handle and less likely to crack and fracture than traditional CN membranes. Pure surface, no additional smoothing treatment or surfactants. Non-sterile version is bright white with an accurate pore structure and highly regulated density for accuracy. Medium-fast flow rates with reproducible loading capacity. Clean-edge processing ensures easy separation from stack and less curl. Autoclavable. Use for clarification or sterilization of aqueous solutions, cytology, yeast and mold virus concentration, HPLC sample preparation of aqueous solutions, OSHA particle analysis, food and beverage microbiological QA/QC. MCE is the standard for microbiological growth and colony counting methods.
