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.

Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed).
More absorbent than Grade 1. In addition to general filtration in the 8 μm particle size range, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials.
Also used for monitoring specific contaminants in the atmosphere and in soil testing.

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 54: 22 μm*
Very fast filtration and high wet strength makes this grade very suitable for vacuum
assisted fast filtration of difficult coarse or gelatinous precipitates.
Grade 41: 20 μm*
The fastest ashless filter paper, recommended for analytical procedures involving coarse particles or gelatinous precipitates (e.g. iron or aluminum hydroxides).
Also used in quantitative air pollution analysis as a paper tape for impregnation when
determining gaseous compounds at high flow rates.
