Whatman Reeve Angel Grade 202 is a general qualitative filter with creped surface and medium filtration speed. Faster than grade 201 and retain large crystalline coarse particles. Widely used in industrial laboratories and students laboratories for routine filtration. The filter is wet-strengthened with a small amount of chemically stable resin to extend the life of the filter and improve handling. Normal qualitative applications will not introduce any significant impurities into the filtrate. However, it is not recommended for Kjeldahl nitrogen analysis. 100 circles/box.
