ME25/41 ST Membrane Circles green, Mixed esters, 0.45µm, 3.1 black grid, sterile, 47mm 100/pk

Overview

Whatman™ mixed cellulose ester (MCE) membranes are composed of cellulose acetate and cellulose nitrate. These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters.

• 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.
