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.

Grade 3: 6 μm, (Medium flow, thick filter paper)
Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging.
The extra thickness gives increased wet strength and makes this grade highly suitable for use in Büchner funnels.
The high absorbency is particularly valuable when the paper is used as a sample carrier.

Grade 43: 16 μm*
Intermediate in retention between Grades 40 and 41, and twice as fast as Grade 40.
Typical applications include foodstuffs analysis, soil analysis, particle collection in
air pollution monitoring for subsequent analysis by XRF techniques, and inorganic
analysis in the construction, mining, and steel industries.
Grade 40: 8 μm*
The classic general purpose ashless filter paper with medium speed and retention.
Typical applications include gravimetric analysis for numerous components in cements,clays, iron, and steel products; as a primary filter for separating solid matter from aqueous extracts in general soil analysis; quantitative determination of sediments in milk, and as a pure analytical grade clean-up filter for solutions prior to AA
spectrometry.
Also used as a high-purity filter in the collection of trace elements and radionuclides from the atmosphere.
Grade 42: 2.5 μm*(Ashless Grades)
Used for critical gravimetric analysis with the finest particle retention of all
Whatman cellulose filter papers.
Typical analytical precipitates include barium sulfate, metastannic acid, and finely precipitated calcium carbonate.
Lenses and other optical surfaces made from glass, quartz or plastic can be easily
scratched if you do not clean them with a very soft surface.
High-quality Whatman
lens cleaning tissue provides the solution. The tissue is chemically pure and free
from silicones and other additives.
Most importantly, it can be relied on to safely remove surface moisture and grease.
