A general qualitative filter with creped surface. High filtration speed and high loading capacity. 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.
