Ahlstrom-Munksjö’s qualitative grades of filter paper are 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. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions.
