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

• Filters coarse particles
• Medium filtration speed
• Creped for increased efficiency

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.
