Whatman MCE filters from Cytiva business are composed of cellulose acetate and cellulose nitrate, giving the membrane a more uniform surface than pure nitrocellulose filters. Browse Cytiva's other MCE filter options to find the right filter for your application.

MCE filters support microbiology applications such as E. coli culturing. The porous membrane structure enables the uptake of growth media to the bacterial colonies without chemically inhibiting their growth. The gridded surface simplifies visual enumeration of bacteria, including E. coli, enterococci, clostridia, fecal coliforms, staphylococci, and Pseudomonas aeruginosa.

Plain and gridded MCE membrane options are available. The gridded option has grid lines spaced at 3.1 mm intervals. Grids are nontoxic and do not inhibit bacterial growth, ensuring sample integrity.
