تفاصيل

This product is a slow-speed quantitative filter paper designed for precise gravimetric analysis and quantitative chemical filtration. Manufactured from high-purity cotton fiber, it undergoes acid treatment with hydrochloric and hydrofluoric acid followed by distilled water washing to minimize residual ash content to less than 0.01%. With a pore size of 1–3 μm and a filtration speed between 70–140 seconds, this filter paper is suited for retaining fine precipitates in weight-based analytical procedures. The consistent grammage of 80±4 g/m² ensures reliable reproducibility across experiments. Available in diameters including 7 cm, 9 cm, and 11 cm, it supports standard laboratory filtration tasks where low ash interference and high precision are required, making it a staple for routine quantitative analysis in research and quality control settings.

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.
