Ahlstrom-Munksjö manufactures a range of extremely pure, acid-washed filter papers for use in analytical and gravimetric analyzes. The quantitative varieties are made from high quality cotton linters, which are made with ultra-pure deionized water and further treatment with dilute acid to remove any remaining organic and inorganic impurities. All quantitative varieties are produced in a strictly controlled environment to ensure high uniformity and high purity. These filters are treated with a strong acid to remove traces of metal and create high wet strength and chemical resistance. They are suitable for standard gravimetric analyzes and in sample preparation for analyzes using instrumental techniques. They are used in particular for Büchner Filtration, where the robust, soft filter surface enables easy removal of deposits. Hardened low-ash type (ash content 0.01%) 388 is usually used for coarse and voluminous deposits such as iron, aluminum and chromium hydroxide as well as for Si determination and in steel and pig iron analysis.
