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.

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.
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 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.
Grade GF/C: 1.2 μm*
Combines fine particle retention with good flow rate.
The standard filter in many
parts of the world for the collection of suspended solids in potable water and natural
and industrial wastes.
Fast and efficient clarification of aqueous liquids containing
low to medium levels of fine particulates.
Widely used for cell harvesting, liquid scintillation counting, and binding assays where more loading capacity is required.
