Are reagent bottles important for the shelf life of chemical reagents?
Chemical reagents are relative reference substances for chemical research and component analysis. Unlike foods and pharmaceuticals, chemical reagents generally have no shelf life requirements or restrictions, but if care is not taken, reagent bottles directly affect the shelf life of reagents.
The shelf life of chemical reagents is affected by many factors. When using it, it is necessary to judge whether the reagent has deteriorated and whether it can be used continuously, in addition to the actual work such as the properties of the reagent itself and the storage conditions. Reagent bottles are special containers used to store a variety of reagents and also affect their shelf life. This translates into two main aspects.
1. Applicability: There are thousands of chemical reagents, and the properties of the reagents are different, so the requirements for packaging containers are also different. For example, hydrofluoric acid strongly corrodes objects containing metals, glass, and silicon, so you should use PET bottles. For chemical reagents such as silver nitrate and iodine that are easily decomposed, volatilized, sublimated, and reacted with light, select a brown bottle. A container for maintaining the stability of reagents.
2. Sealability: Vial sealability is another important factor that affects reagent lifetime. If the sealing does not reach the standard, it is easy to lead to the volatilization of the reagent and the invasion of external impurities, which affects the efficiency of the reagent.
The effect of reagent bottles on the shelf life of chemical reagents is primarily reflected in their applicability and sealing performance. If a reagent deteriorates, it cannot be reused without affecting the results of experiments or tests.
