Grade 5: 2.5 μm*
The maximum degree of fine particle filtration in the qualitative range.
Capable of retaining the fine precipitates encountered in chemical analysis.
Slow flow rate.
Excellent clarifying filter for cloudy suspensions and for water and soil analysis.
Also available prepleated as Grade 5V.

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 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.
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.
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.
