Ahlstrom 610 Standard Qualitative Filter Papers

Ahlstrom 610 Standard Qualitative Filter Papers are 1.5µm slow speed filters designed to retain fine particles encountered in qualitative analysis. Grade 610 is widely used for water analysis, biological products, and fine participates such as col-precipitated barium sulfate. It is also used in Buchner funnels and to clarify cloudy suspensions.

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. Not recommended for use in vacuum work or when went handling is required.
