What are the main classifications of reagent bottles

The preservation of reagents is inseparable from the outer packaging of reagent bottles. Different reagents need to be stored in plastic packaging. Commonly used reagent storage containers are generally stored in glass reagent bottles. Reagent bottles can be divided into glass bottles and plastic bottles in terms of material. In terms of the types of reagents stored, the bottle mouth mainly includes screw mouth and frosting.

Reagent bottles mainly include: grinding reagent bottles, wide mouth reagent bottles, screw mouth reagent bottles, chemical reagent bottles, etc. Some reagents need to be stored in plastic reagent bottles. For example, hydrofluoric acid is an aqueous solution of hydrogen fluoride, which is highly corrosive. Hydrofluoric acid can dissolve many glass (silica) that cannot be dissolved by other acids, but it does not react with plastics. Therefore, plastic reagent bottles are generally used to contain hydrofluoric acid. Plastic reagent bottles are also used for solid caustic soda, alkali lime and other reagent containers, and PET plastic reagent bottles are also used for washing bottles containing distilled water.

Reagent bottles are mainly divided into fine mouth bottles and wide mouth bottles in shape, and are divided into colorless and brown in color. Wide mouth bottles contain solid drugs, brown bottles contain solids that are easy to decompose when exposed to light, fine mouth bottles contain liquids, and brown fine mouth bottles contain liquids that are easy to decompose when exposed to light. Corks shall be selected according to the standard cork specifications consistent with the pH of solids and solutions.
