Ahlstrom Filtration Grade 610 Standard Non Wet-strengthened Qualitative Filter Paper, 20.5 cm dia

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. Ahlstrom offers a complete range of low ash filter papers for general laboratory work that provides you with the correct combination of particle retention, filtration speed, loading capacity and wet-strength. All our qualitative grades consist of > 95% super refined a-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. 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 cold precipitated barium sulfate. Ahlstrom 610 is also used in Buchner funnels and to clarify cloudy suspensions.
