Laboratory Reagent Bottle Use Precautions

- Jul 26, 2019-

The glass bottle of the reagent bottle has colorless and brown color; wide mouth and fine mouth; grinding mouth and no grinding mouth, etc. The jar is used to hold the solid reagent, the fine bottle is filled with the liquid reagent; the brown bottle is used for the light-proof reagent, and the grinding stopper bottle can prevent the moisture absorption and the concentration change of the reagent, and the reagent bottle is not heat-resistant.

Here are some notes on using the reagent bottle in the lab:

(1) When the plugged reagent bottle is not used, put a paper strip between the stopper and the frosted surface of the bottle to prevent sticking. As mentioned earlier, all reagent bottles cannot be used for heating.

(2) According to the physical and chemical properties of the reagents, the general principle of selecting the required reagent bottles is: the solid reagents are used one by one, and the liquid reagents are used - the fine-mouth bottles are used to contain the reagents which are easily decomposed or deteriorated by light. The brown bottle is used to hold the low-boiling and volatile reagents. One of them is a frosted glass reagent bottle, and the alkaline reagent is used with a rubber stopper reagent bottle. If the reagent has the above-mentioned multiple physical and chemical indicators, it can be comprehensively considered according to the above principles, and an appropriate reagent bottle is selected.

(3) Some special reagents, such as hydrofluoric acid, cannot be used in any plastic bottle.

Container glass equipment, in addition to the above several types, according to different requirements when taking liquid, there are two types of bottles, three bottles, four bottles, and lower mouth bottles (also known as faucet bottles).
