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.
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.
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.
