Mixed Cellulose Ester(MCE) membrane filter is composed of cellulose acetate and cellulose nitrate. Because MCE membrane is biologically inert, it is 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 General Purpose Examination of all Microorganisms, 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, analysis of yeast and mold and Legionellasp. Examination of White, beige colonies. Providing contrast between residue or cell colors and the filter without having to counter-stain the membrane.
