The reagent bottle is divided into narrow mouth and wide mouth. The wide-mouth bottle is used to hold solid reagents and the narrow-mouth bottle is used to hold liquid reagents. The color is clear and amber. The amber reagent bottle is used to hold light-decomposible reagents or solutions, such as io-dine solution, silver nitrate, po-tassium per-manganate, potassium io-dide, etc. Grinding stopper bottle can prevent moisture absorption and concentration change of reagent, keep sealed and prevent leakage of reagent. It can be filled with a-cid, non-strong alkaline reagent or organic reagent solution and other substances which have little corrosiveness to glass. When using, we should pay attention to the original bottle stopper. The size of the bottle and the stopper should be consistent to facilitate sealing, avoid the evaporation of solution and change the concentration. When the reagent bottle is not in use, it should be cleaned and lined with a piece of paper between the bottle mouth and the stopper, so as not to stick to each other after a long time of shelf. Reagent bottles can only be used for storage reagents, can not be used as heating utensils, can not inject quenching and shock heating reagents, and can not be prepared solution in the bottle and long-term storage of concentrated alkali and salt solution. Reagent bottles are not heat-resistant. The maximum tolerance temperature is 100 ℃.
