Chemistry dictionary tells you how to use Plastic reagent bottle and precautions. Reagent bottles are mainly used to contain chemical reagents, so they are also called reagent bottles.

Because Plastic reagent bottles are only used as reagents for storage at room temperature, they are generally made of ordinary soda-lime glass. In order to ensure a certain strength, the bottle wall is generally thicker. In addition to fine-mouthed and wide-mouthed reagent bottles, there are two types of colorless and brown (brown) reagent bottles, with plugs and without plugs. Those with glass stoppers should have internal frosting treatment regardless of whether they are narrow or wide mouth. If there is no plug, there is no need for internal frosting, and a certain specification of non-glass plugs, such as rubber plugs, plastic plugs, and cork plugs. In recent years, various practical Plastic reagent bottles have appeared on the market, making this kind of containers colorful.

The specifications of the Plastic reagent bottle are expressed in terms of volume, ranging from as small as 30mL and 60mL to several thousand to tens of thousands of milliliters.

Precautions for the use of plastic reagent bottle

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

(2) The general principle of selecting the required reagent bottles according to the physical and chemical properties of the reagents is: to contain solid reagents one by one, choose wide-mouth bottles, and for liquid reagents-choose narrow-neck bottles, which contain reagents that are easy to decompose or deteriorate when exposed to light. Choose brown bottles for low-boiling and volatile reagents one by one, choose frosted glass reagent bottles, one for alkaline reagents one choose reagent bottles with rubber stoppers, and so on. If the reagent has multiple physical and chemical indicators mentioned above, you can consider the above principles and choose an appropriate reagent bottle.

(3) Some special reagents, such as hydrofluoric acid, cannot be used in any glass reagent bottles, but plastic reagent bottles are used.
