what is beaker used for

A beaker is a common type of laboratory glassware used for various purposes such as preparing and holding solutions, measuring liquids, heating them over a Bunsen burners flame, and collecting them in a titration experiment. Beakers are generally cylindrical containers with a flat bottom, an open top, and a small spout to aid pouring. They are available in a wide range of sizes, from one milliliter up to several liters, and are commonly made of glass, metal, or certain plastics. Beakers are used in most chemical, biological, clinical, and industrial laboratories, as well as in other industrial situations where testing is carried out. They are essential for containing chemical reactions, measuring liquids, and holding samples for later use).
