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.

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.
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.
Offers fine particle retention and high flow rate, as well as good loading capacity.
Used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for filtration of water, algae and bacteria cultures, food stuff analyses, protein filtration, and radioimmunoassay of weak ß emitters.
Recommended for gravimetric determination of airborne particulates, stack sampling, and absorption
methods of air pollution monitoring.
