A vessel with a thin cylindrical neck used in chemical experiments for reactions, distillation, measuring volumes, bacterial cultivation, etc. It is generally made of glass, but can also be made of quartz, metal, or synthetic resin. A vessel with a spherical body is called a round-bottom flask, one with a flat bottom is called a flat-bottom flask, and one with a conical body is called an Erlenmeyer flask. Many flasks also have special shapes depending on the shape of the neck or the purpose.
