Cytiva Ester Circles, 47mm Diameter, Mixed Cellulose Ester ME 25 Plain, 0.45um Pore Size, 100 per pack

Whatman™ Mixed Cellulose Ester (ME 25) Membrane Filter, 0.45 µm, 47 mm (plain, 100/pack) — a mixed cellulose ester (a blend of cellulose nitrate and cellulose acetate) membrane offering a highly uniform pore structure with lower extractables than pure nitrate. The 0.45 µm rating is the classic pore size for routine microbiological analysis and general clarification.

The MCE matrix combines high flow rate with a smooth, wettable surface ideal for colony visualization and gravimetric work.
