Reagent bottle is a type of laboratory glassware used for storing chemical substances, specifically reagents. Reagents are chemicals or compounds that are used in chemical reactions or analysis to produce a chemical change or to detect, measure, or qualitatively analyze other substances.
Reagent bottles are designed to safely contain and protect reagents from contamination or degradation. They are typically made of glass, although plastic reagent bottles are also available. The bottles come in various sizes and shapes, but they commonly have narrow necks with ground glass stoppers or screw caps to create a tight seal and prevent evaporation or leakage.
