Reagent bottle use precautions

1. To prevent adhesion, slip the paper between the bottle stopper and the bottle mouth when not using the reagent bottle. As previously stated, none of the reagent bottles can be heated.

2. The general principle for selecting reagent bottles based on the physical and chemical properties of the reagents is: dress up solid reagent selection jar, holding liquid reagent - choose fine mouth bottle, all see light is easy to break down, or metamorphic reagent to choose brown bottle, holding low boiling point. The volatile reagent is held in frosted glass reagent bottles, while the alkaline reagent is held in rubber plug reagent bottles, and so on. If the reagent has the aforementioned multiple physical and chemical indexes, the appropriate reagent bottle can be chosen using the aforementioned principles.

3. Certain reagents, such as hydrofluoric acid, are not available in glass reagent bottles and must be used in plastic bottles.
