CHM Quantitative filter paper

These CHM® filter papers are used for quantitative analysis and designed for preparation of samples and gravimetric analysis. They are made of refined pulp and linters with virtually 100% of alpha-cellulose content.

These filter papers are guaranteed free of possible residual acids used in some production methods. Extremely low percentage of ash content (maximum ash content of <0.007%).

Ashless filter papers for quantitative analyses are suitable for Büchner funnels and for filtration under vacuum. Suitable for gravimetric measurements of gypsum/lime suspensions in power plants.

F2043 Grade is particularly applied in metallurgical industry laboratories for metal tests. Typical applications include foodstuffs analysis, soil analysis, particle collection in air pollution monitoring, COD and TOC determination, inorganic analysis in the construction, mining and steel industries. They are also used for Blaine test in the cement industry (standards UNE 80-112-91 and EN 196-6), and to carry out other chemical analysis on cement.
