Cytiva Whatman™ Qualitative Filter Paper: Grade 4 Circles
A standard grade filter used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
