ME25/21 (Mixed Cellulose Ester) STL Membrane Circle, white, 47 mm 0.45 µm, 3.1 mm black grid, sterile, for Membrane-Butler, 400/pk

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.
