Designed for slow flow filtration, it excels in capturing fine particles during qualitative analysis, making it a staple for water testing, biological samples, and fine precipitate clarification. Crafted from over 95% alpha-cellulose, these untreated papers offer consistent performance in gravity and quadrant folded applications, ensuring reliable lab results every time. ## Description 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. 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. Qualitative analysis, low ash content 0.06 percent, untreated, consistent performance, wet-strengthened grades, custom cut. 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 coldprecipitated barium sulfate.
