Filter Paper, round, Grade 202, 400 mm, wet-strengthened, 100 pc/PAK

A general qualitative filter with a creped surface. Faster than Class 201 and retains coarse crystalline coarse particles. Widely used in industrial and student laboratories for routine filtration.

-
• Filters coarse particles
• Medium filtration speed
• Crèped for increased efficiency and filter life compared to smooth filter papers of the same diameter

The filter is wet strengthened with a small amount of chemically stable resin to extend filter life and improve handling. Normal qualitative applications will not introduce significant contaminants into the filtrate. However, it is not recommended for Kjeldahl nitrogen analysis.
