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 gridded filters have clearly defined grid lines spaced at 3.1 or 5 mm intervals.
The special ink used is nontoxic and completely
free from bacterial growth inhibitors.
Grade 44: 3 μm*
Thin version of Grade 42 retaining very fine particles but with lower ash weight per sample and almost twice the flow rate of Grade 42.
Cellulose extraction thimbles are produced from high-quality alpha cellulose cotton
linter and have excellent mechanical strength and retention.
Standard single thickness thimbles have a wall thickness of approximately 1 mm
(10.0 μm nominal particle retention).
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
