Validity Period Of Chemical Reagents

Chemical reagents are affected by external factors such as temperature, light irradiation, air and moisture during storage, transportation and sales, and are prone to physical chemistry such as deliquescent, mycin, discoloration, polymerization, oxidation, volatilization, sublimation and decomposition Change, make it invalid and unusable. Therefore, it is necessary to adopt reasonable packaging, appropriate storage conditions and transportation methods to ensure that the chemical reagents do not deteriorate during storage, transportation and sales. Some special requirements for storage and transportation should be handled in accordance with special requirements. Some chemical reagents have a certain shelf life, so be careful when using them.

The validity period of chemical reagents varies greatly with the change of chemical properties. Under normal circumstances, chemically stable substances have a longer shelf life and simpler storage conditions.
