Whatman 10406806 ME25/21 Mixed Cellulose ester circles (MCE), white, plain, 0.45 µm, 25 mm, 100/pk

Mixed cellulose ester, WME range, circles, gridded. 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.

Features:
Sterile options available for critical applications.
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.
Suitable alternative to DISCONTINUED Pall SKU 61491.
