3、 Advanced pure GR science popularization:

GR (Guaranteed Reagent) is a purity specification for a chemical reagent, classified as a first grade product with a dark green label. It is used for precision analysis experiments and can serve as a reference substance. It has a very high content and purity of principal components, suitable for precise analysis and research work, and some can be used as reference materials. The purity of GR reaches 99.8%, with the lowest impurity content, making it suitable for important and precise analysis and scientific research work. This reagent has the highest purity and the lowest impurity content, making it suitable for important and precise analysis and scientific research work. It uses green bottle labels.

4、 Difference from general reagents

The purity of high-grade pure reagents usually reaches 99.8%, with extremely low impurity content, suitable for important and precise analysis and scientific research work, using green bottle labels. And general reagents, such as analytical grade (AR) or chemical grade (CP), although can also be used for scientific research and chemical experiments, their purity and impurity content are relatively high, making them suitable for general scientific research and demanding quantitative and qualitative analysis experiments. High grade pure reagents have very low impurity content and are suitable for precision analysis experiments and scientific research, while general reagents have relatively high impurity content and are suitable for general chemical experiments with low requirements.
