Chemical reagents will be affected by external factors such as temperature, light irradiation, air and moisture during storage, transportation and sales, and are prone to physical and chemical changes such as deliquescent, mycin, discoloration, polymerization, oxidation, volatilization, sublimation and decomposition, making them ineffective and unusable. Therefore, it is necessary to adopt reasonable packaging, appropriate storage conditions and transportation methods to ensure that chemical reagents do not deteriorate in the process of storage, transportation and sales. For some special requirements for storage and transportation, it should be handled according to special requirements. Some chemical reagents have a certain shelf life, so you must pay attention to them when using them.
The expiration date of a chemical reagent varies greatly depending on the chemical properties of the chemical. In general, the longer the shelf life of a chemically stable substance, the easier the storage conditions.
