Cellulose filters are used in qualitative analytical techniques to determine and identify materials.
Prepleated qualitative filters are available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

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 prepleated as Grade 4V.

Whatman chromatography paper media are made from specially selected cotton cellulose.
They are rigorously quality controlled for characteristics important to the chromatographer and to ensure uniformity within
the grade.
Features and benefits
• Pure cellulose produced entirely from the highest quality cotton linters
with no additives of any kind
• Manufactured and tested specifically for chromatographic techniques –
this ensures the wicking capability and uniformity of capillary action that
are important in chemical separations
• Also widely used in protein and nucleic acid blotting

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.
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.
