APPLICATIONS:
1. Qualitative analysis pretreatment;
2. Filtration of precipitates, such as ferric hydroxide, lead sulphate, calcium carbonate;
3. Seed testing and soil analysis.
Qualitative filter papers are made of 100 % linter cotton, manufactured by modern paper-making technology. This kind of filter paper is generally used for qualitative analysis and solid-liquid separation. The quality of the filter paper is reliable and stable based on extensive research in more than 20 years.
