General description
A general qualitative filter with creped surface. 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. Reeve Angel products are designed for routine, repetitive applications for which an inexpensive product is acceptable, such as qualitative analysis. Reeve Angel products deliver as promised, every time.
Features and Benefits
- Filters coarse particles
- Medium filtration speed
- Crêped for increased efficiency and filterlife compared to smooth filter papers of same diameter
