Whatman™ 7140-104 WME Mixed Cellulose Ester Membrane Filter , Pore Size: 0.45µm, Diameter: 47mm (Pack of 100)This Whatman™ mixed cellulose ester membrane (WME) is composed of cellulose acetate and cellulose nitrate. The membrane is characterized by a smoother and more uniform surface than pure nitrocellulose filters. The color contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue. In microbiological colony counting procedures, the color contrast between the surface and the colonies facilitates the counting process. Steam autoclavable. Type: Plain. Diameter: 47mm. Pore Size: 0.45µm. Burst Strength: > 10psi. Maximum Service Temperature: 130°C. Porosity: 74 to 77%. Solvent Resistancy: Medium. Protein Binding: Medium.
