GE Healthcare Life Sciences offers qualitative, ashless, and technical filter papers that cover broad applications in laboratory and industrial applications. We also offer application specific filters and phase separator papers.
The different grades of cellulose filters offer increasing degrees of purity, hardness, and chemical resistance. Some grades are also available in a prepleated format, enabling improved flow rate and increased loading capacity.
Whatman cellulose filters are manufactured from high quality cotton linters which have been treated to achieve a minimum alpha cellulose content of 98% to maintain guaranteed quality, reproducibility, and uniformity. The filters are tested for basic weight, thickness, air flow, and mechanical strength. They are mainly used for sample clarification or precipitate recovery before material identification or quantification in areas such as pharmaceutical, chemical, environmental testing, food and beverage, mining, cement and many other industries.
