Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.
Reagent Bottles are useful for storing both liquids and powders. These bottle mouth and stopper stem are machine ground. This glass-to-glass joint is an air-tight seal without the use of a rubber or cork stopper.
