WCN Memb WG 0.45umx47mm/200 Sterile

• 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.

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.
