Precautions for using laboratory reagent bottles

Glass bottles containing reagents, whether colorless or brown; Wide mouth and narrow mouth; There are various types of grinding, no grinding, etc. Wide mouthed bottles are used to hold solid reagents, while narrow mouthed bottles are used to hold liquid reagents; Brown bottles are used for light proof reagents, while ground stoppered bottles can prevent moisture absorption and concentration changes. Reagent bottles are not heat-resistant

(1) There is a stopper

(2) The general principle for selecting the required reagent bottles based on the physical and chemical properties of the containing reagents is: use a wide mouthed bottle to hold solid reagents, use a fine mouthed bottle to hold liquid reagents, use a brown bottle to hold reagents that are prone to decomposition or deterioration when exposed to light, use a frosted glass reagent bottle to hold low boiling and volatile reagents, and use a rubber stopper reagent bottle to hold alkaline reagents, etc." When there are multiple physical and chemical indicators mentioned above, a suitable reagent bottle can be selected based on the above principles.

(3) Some reagents, such as hydrofluoric acid, cannot be packaged in any glass reagent bottle and should be packaged in plastic bottles.

Container glass instruments, in addition to the above-mentioned types, there are also various types of bottles available for selection, such as two necked bottles, three necked bottles, four necked bottles, and lower necked bottles (also known as bottles), depending on the different requirements for liquid retrieval and storage.
