Sartorius, 11303--25------N, Cellulose Nitrate (Mixed Cellulose Ester) Membrane Filter Discs / Type 11303, 1.2 µm pore size, 100 pieces per pack

Top Features of Cellulose Nitrate (Mixed Cellulose Ester) Membrane Filter Discs
Ideal for several general laboratory applications
High, non-specific absorption
Hydrophilic, with high flow rates
Available in a range of pore sizes and diameters up to 293 mm

Cellulose nitrate (CN) - or mixed cellulose ester (MCE) - membrane filters are composed of cellulose nitrate and a small content of cellulose acetate. Cellulose nitrate membrane filters are hydrophilic, have high flow rates thanks to their symmetrical structure and are compatible with aqueous solutions (pH 4 – 8), hydrocarbons and several other organic solvents.
