Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

General purpose qualitative filter papers
Supplier: Ahlstrom-Munksjö
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. Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications.

High purity qualitative filter paper
Supplier: Ahlstrom-Munksjö
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.
