Ahlstrom Grade 615 Qualitative Filter Paper – 100 Circles

Ahlstrom Grade 615 Qualitative Filter Paper – 100 Circles 

Ahlstrom 615 is a fast filter grade with a rough surface that is intermediate in properties between Grade 617 and Grade 631. Low ash grade contains more than 95% super refined alpha-cellulose and linter fibers. 

Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications. These grades contain a high level of alpha-cellulose that provides high purity but will weaken when wet. The inherent strength of standard (untreated) grades does not pose a problem when they are used in routine quadrant folded applications. We do not recommend these grades for use in vacuum work or when wet handling is required.
Ahlstrom’s qualitative grades of filter paper are, by definition, recommended for use in analytical methods, which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance.
