Ahlstrom Qualitative Filter Papers, Grade 610

Ahlstrom Grade 610: 1.5 m - Slow Speed (non wet-strengthened). This grade is a slow flowing filter designed to retain fine particles encountered in qualitative analysis. Ahlstrom 610 is widely used for water analysis, biological products and fine precipitates such as coldprecipitated barium sulfate. Ahlstrom 610 is also used in Buchner funnels and to clarify cloudy suspensions.

Standard Grades (Non Wet-Strengthened). 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. Ahlstrom does not recommend these grades for use in vacuum work or when wet handling is required.
