Grade 631 Qualitative Filter Papers

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. Grade 631 Qualitative Filter Papers:

Key Features

  • Quantitative analysis
  • Low ash content 0.06%
  • Untreated High wet-strength
  • Consistent performance
  • Wet-strengthened grades available
  • Custom Cut
  • Bulk packaging

Standard Grades (Non-Wet-Strengthened) Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications. Grade 631 Qualitative Filter Papers 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 631: 10um, Medium Speed. This grade is used for the filtration of coarse particles and gelatinous precipitates such as ferric aluminum and magnesium hydroxides. Ahlstrom 631 is used in air monitoring and gas filtration when a high flow rate is needed. This grade is also found in routine cleanup analysis of insoluble liquids such as biological fluids and organic elements.
