Macrofiltration
High-purity qualitative and quantitative filter paper covering a wide range of laboratory applications, binder-free glass and quartz microfiber filters dedicated to environmental analyses.
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.
We manufacture a series of extremely high purity, acid washed quantitative 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.
We offer a full range of glass micro-fiber filters manufactured from 100% pure borosilicate glass. Because of their intrinsic properties, these filters have wide applications in many areas of laboratory analysis, especially when fine filtration and high loading capacity is required. Glass micro-fiber filters are also found in the filtration of hot gases and liquids, and in pre-filtration.
Ahlstrom micro-quartz filters represent a complete offer for airborne particulate monitoring in high temperatures and aggressive atmospheres or when the lowest level of Trace Elements Analysis is required. These extremely pure 100% quartz filters have a temperature stability up to 900°C.
