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.
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 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 93: 10 μm*
This filter paper is intermediate in speed and retention between Grades 1 and 4.
Available in a dispenser pack, which can be attached to the wall or bench, placed on a
shelf either upright or flat, and used as a normal carton or as a convenient dispenser.
The envelopes are released individually for easy one-at-a-time removal.
Package and envelopes are clearly marked for size and content.
