Description
Introduction：
Quantitative filter paper is mainly used for greyscale analysis experiment after filtration, that is, gravimetric analysis test and corresponding analysis test in quantitative chemical analysis, the ash weight of each filter paper after greyscale is a fixed value; Qualitative filter paper is used for general filtration, that is, qualitative chemical analysis and corresponding filtration separation.
Application:
1. Precise quantitative analysis;
2. Liquid purification;
3. Analysis of separation air or water.
