Product Brand: Bright Quantitative Filter Paper
Product Material: Made of cotton fiber
Product Introduction:
Quantitative filter paper is mainly used for the filtration and weighing analysis experiments after filtration, that is, weight method analysis experiments and corresponding analysis experiments in quantitative chemical analysis. The ash weight after the filter paper is ashed is a constant value; qualitative filter paper is used for general filtration, that is, qualitative chemical analysis and corresponding filtration separation.
During the manufacturing process of quantitative filter paper, the pulp is treated with hydrochloric acid and hydrofluoric acid, and then washed with distilled water to remove most of the impurities in the paper fiber. Therefore, the residual ash after burning is very small and has almost no impact on the analytical results, making it suitable for precision quantitative analysis.
