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 and benefits:-
• 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
• Thermally stable
