Qualitative Filter Paper (Disc and Square)

The qualitative filter paper includes standard filter papers and wet-strengthened filter papers, and the ash content is less than 0.15%.

The standard qualitative filter paper is used to identify the properties of substances in qualitative analysis.

Wet strength qualitative filter paper contains a small amount of chemically stabilized resin, thereby enhancing the wet strength. This does not introduce any obvious impurities into the filtrate. However, because of resin containing nitrogen, these grades of filter paper cannot be used for the determination of Kjeldahl nitrogen.

Quantitative Filter Paper (Disc and Square)

Quantitative filter paper ash content is less than 0.01%.
Mainly used for the filtration after the filtration, that is, the weight method analysis test and the corresponding analysis test in the quantitative chemical analysis. The ash weight of each filter paper is a fixed value.

The hardened ashless filter paper has a very low ash content, and acid hardening increases wet strength and chemical resistance. It can be applied to most major filtration processes because of its hard surface. There are different grades available in HAWACH.
