Qualitative filter paper, circles, 55mm, grade 292
AHL-3.205.055

High-purity qualitative and quantitative filter paper covering a wide range of laboratory applications.

Applications for qualitative filter papers

Ahlstrom 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. These filters are often used in routine separation work that still requires high purity and consistent performance.

Our qualitative filter papers cover a wide range of laboratory applications including:

  • Liquids clarification
  • Qualitative analytical separations for precipitates
  • Buffers filtration
  • Soil analysis 
  • Food and beverage testing

Applications for quantitative filter papers

Ahlstrom manufactures a series of extremely high purity, acid washed filter papers, from top quality cotton linters using ultra-pure, deionized water and further treated with dilute acid to remove any remaining organic and inorganic impurities.

Our quantitative filter papers cover a wide range of laboratory applications including:

  • Analytical analysis
  • Gravimetric analysis

All Ahlstrom qualitative and quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.
