Whatman cellulose filters are manufactured from high-quality cotton linters which have been treated to achieve a minimum alpha cellulose content of 98%. These cellulose filter papers are used for general filtration and exhibit particle retention levels down to 2.5 µm. Whatman offers a wide choice of retention/flow rate combinations to match numerous laboratory applications.
The different groups of filter paper types offer increasing degrees of purity, hardness and chemical resistance.
