qpore® Grid Membrane Filter CME, sterile, 0.8 µm, Ø 47 mm, perforated, suitable for dispenser

qpore® cellulose ester (CME) grid membranes consist of cellulose acetate and cellulose nitrate. Because the CME membrane is biologically inert, it is widely used in analytical and research applications. CME membrane filters are characterized by a smoother and more uniform surface than pure nitrocellulose filters. The color contrast of the filter surface facilitates particle detection and minimizes eye fatigue.

Many microbiological techniques include colony counting after incubation as a standard method of quantification. Grid filters have clearly defined grid lines at 3.1 mm intervals. The special ink used is non-toxic and completely free of bacterial growth inhibitors. White discs with grids are intended for the recovery and retention of E. coli bacteria in water / wastewater analysis and other microbiological tests.
