A general qualitative filter with creped surface. Widely used in industrial or student laboratories for routine filtration.

• High filtration speed
• Retains coarse or gelatinous particulates
• Unique creped gray surface provides optical contrast for white or dark filtrates

The filter is wet-strengthened with a small amount of chemically stable resin to extend the life of the filter and improve handling

Designed for routine and repetitive applications for which an inexpensive product is acceptable, such as qualitative analysis.

Normal qualitative applications will not introduce any significant impurities into the filtrate. However it is not recommended for Kjeldahl nitrogen analysis.
