Requirements for the use of reagent bottles in chemical reagents
Author:
HF solution cannot be stored in glass bottles due to corrosion of glass. Plastic bottles or lead containers can be used instead. Other reagents are generally stored in glass bottles. General solid reagents are stored in wide mouth bottles, while general liquid reagents are stored in fine mouth bottles. Reagent bottles containing alkaline substances (such as NaOH, Na2CO3, Na2S, etc.) or water glass must be stoppered with rubber or cork. Because alkaline substances or water glass can react with silica in the glass, resulting in the adhesion between the bottle and the stopper. It is advisable to use glass stoppers without special instructions. Reagents that are easy to decompose when exposed to light should be stored in brown wide mouth bottles or thin mouth bottles. For example, AgNO3, chlorine water, hydrogen peroxide, bromine water, and unstable organic compounds are generally stored in colorless reagent bottles. Drip bottles cannot store liquid reagents that are prone to evaporation, volatilization, and have a corrosive effect on the adhesive head. Dropping bottles are generally not used as long-term storage reagents. Reagents that are easily decomposed by light should be stored in brown bottles.
