Description

The mall specializes in producing and selling high-purity experimental products for "scientific research institutes, universities and other" scientific research institutions and laboratories. For experiments, we should buy high-cost and high-purity products instead of low-cost and low-purity products. We should buy according to the actual use. Although the purity of industrial products looks the same. We should avoid low purity industrial products entering the laboratory, which will affect the accuracy of experimental results.

1g-ten percent in the option is equivalent to the platinum carbon catalyst with 1g weight and ten percent platinum content, and other specifications in the option also mean the same.
