Specification of Ester Membranes 12

Sterile Mixed Cellulose Ester Membranes, 1.2 µm

Whatman mixed cellulose ester membranes are composed of cellulose acetate and cellulose nitrate. These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters. Also, the color contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue. The ME range has a lower cellulose acetate content compared to the WME range of membranes.

Excellent contrast for easier particle detection. Grids are nontoxic and do not inhibit bacterial growth, ensuring sample integrity. Black plain and black gridded membranes have a mix of cellulose nitrate and cellulose acetate. The membrane offers a high degree of internal surface area for greater adsorption of product. Higher dirt loading capacity. Biologically inert with good thermal stability. No surfactants to contaminate samples. Uniform microporous structure of membrane gives high flow rates
