an erlenmeyer flask, named after the chemist emil erlenmeyer (1825-1909), is different to a beaker in that it comes with an inverted conical base and a cylindrical neck. there are different types of erlenmeyer flasks for laboratory applications: the narrow neck and wide neck forms. depending on the application the flask may have precision grinding to allow good connection to other containers. \t\t\t \t\t\tthe narrow neck reduces the risk of fluid escaping, especially when boiling or during reactions which agitate the contents. \t\t\t \t\t\tan erlenmeyer flask is useful for mixing fluids or accelerating reactions by stirring or shaking, for example. the erlenmeyer flask is particularly suited for a magnetic stirrer, since it can be placed directly on the stirring platform. a round-bottomed flask, by contrast, must be placed on a cork ring on the stirring platform.
