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.

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
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.
Whatman black mixed cellulose esters are available plain for automatic colony
counting applications, as well as gridded to assist in manual counting procedures.
Black membranes provide contrast between residue or cell colors and the filter
without having to counter-stain the membrane.
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.
Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance.
The membranes have a smooth flat surface and exhibit very low levels of extractables.
