Food testing is an important measure to ensure food safety. Food testing involves many items, mainly including food additives, pesticide residues, veterinary drug residues, toxins, etc. In order to obtain accurate qualitative and quantitative results, each laboratory needs to be equipped with corresponding standard substances, which results in a large number of standard substances. The orderly and reasonable storage of standard substances is not only related to the beauty of the laboratory, but also of great significance to improving work efficiency.
