Mixed Cellulose Esters (MCE)
Membrane Filter
MS® mixed cellulose ester•MCE•membrane filters are composed of cellulose acetate and cellulose nitrate. Because MCE
membrane is biologically inert, it’s one of the most widely used membranes in analytical and research applications. MCE
membrane filter is characterized by a smoother and more uniform surface than pure nitrocellulose filter. Also, the color
contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue.
Many microbiological techniques include colony counting after incubation as the standard method of quantification. Gridded filters
have clearly defined grid lines spaced at 3.1 mm intervals. The special ink used is nontoxic and completely free from bacterial
growth inhibitors. White gridded disks are designed for the recovery and retention of E. Coli bacteria in water/wastewater analysis
as well as other microbiological tests. Black mixed cellulose esters(MCE) are available plain for automatic colony counting
applications, as well as gridded to assist in manual counting procedures. Black MCE membranes provide contrast between residue
or cell colors and the filter without having to counter-stain the membrane.
Membrane solutions, LLC also supply sterile gridded membrane filters with or without pads.
