Description

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 2.5um. We offer a wide choice of retention/flow rate combinations to suit numerous laboratory applications. The different groups of cellulose filters offer increasing degrees of purity, hardness, and chemical resistance.
Qualitative filter papers
These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Fluted qualitative filters are available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Grade 4 (25 um*)
Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide.
Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis.
Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical. Available fluted as Grade 4V.
