About Grade 4 Qualitative Filter Paper, Circle, 150mm

These cellulose filters are used in qualitative analytical techniques to determine and identify materials 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. Note: This data shown may be based on historic Whatman records. As is normal practice, customers should determine and validate for themselves (as necessary) that the products are suitable for their specific application. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
