Storage of chemical laboratory reagents

Solid reagents are typically stored in easy-to-access jars, and liquid reagents are stored in vials. Some small-sized and frequently used reagents, such as indicators, qualitative analysis reagents, etc., can be contained in a dropper bottle. Reagents that are easily decomposed by light should be packed in brown bottles. Although hydrogen peroxide is also a substance that is easily decomposed by light, it cannot be contained in a brown glass bottle. Because the brown glass bottle contains heavy metal oxides, it will catalyze the decomposition of hydrogen peroxide. Therefore, hydrogen peroxide is usually stored in an opaque plastic bottle. Place in a cool dark place. The stoppers of the reagent bottles are generally ground, but the stoppers of the strong alkaline reagent solution should be replaced with rubber stoppers to prevent mutual adhesion for a long time. Reagents for corrosive glass should be stored in plastic bottles. For the storage of flammable, explosive, strong corrosive, strong oxidants and drugs, special attention should be paid to the storage of flammable substances and flammable substances.
