Requirements for reagent bottles of different chemical reagents

Chemical reagents are essential items in chemical laboratories. They are classified into highly toxic, oxidizing, flammable, explosive, corrosive, radioactive, etc. according to the different properties of the reagents. Different reagents have different requirements for reagent bottles.
1. Material
The common materials of reagent bottles are glass and plastic, and hydrofluoric acid solution is a corrosive reagent, which has a strong corrosive effect on glass. Inhalation of vapor or contact with the skin will cause incurable burns. In order to ensure the stability of the reagent , Plastic bottles should be selected when choosing containers.
2. Bottle mouth
Solid reagents and liquid reagents are used in different ways, so the requirements for the bottle mouth are also different. Under normal circumstances, choose a wide-mouth bottle for solid reagents, which is easy to take, and choose a narrow-mouth bottle for liquid reagents, which can prevent the liquid from spilling and volatilization.
3. Bottle stopper
Bottles containing alkaline substances or water glass must use rubber stoppers or cork stoppers, because these substances will react with the silica in the glass, resulting in the adhesion of the bottle mouth and the bottle stopper, which is inconvenient to open and poses a certain danger. .
4. Color
Reagents that are easily decomposed by light should be stored in brown bottles, such as iodine, silver nitrate, nitrate, chlorine water, etc. These substances are easily decomposed after being exposed to light, and the brown color can prevent the irradiation of visible light and prevent the decomposition and deterioration of the reagents.
There are many kinds of chemical reagents, and the selection of appropriate reagent bottles for different reagents is the key to ensuring their stability and the safety of laboratory personnel, which requires great attention.
