Ahlstrom 6170 3300 Qualitative Filter Diameter Review

Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. Qualitative grades consist of greater than 95 percent super refined a-cellulose and linter fibers. Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications. This is an extremely fast filtering grade and has a larger particle retention. Ahlstrom 617, a thicker filter paper with higher loading capacity, is used for rapid filtration of coarse particles and gelatinous precipitates such as in oils and resin solutions.
