Erlenmeyer flasks, commonly known as a conical, are a widely used type of laboratory flask which features a flat, conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
The Erlenmeyer is marked on the side (graduated) to indicate the approximate volume of contents, and has a spot of ground glass where it can be labeled with a pencil. It differs from a beaker in its tapered body and narrow neck.
The conical shape allows the contents to be swirled or stirred during an experiment, either by hand or by a shaker; the narrow neck keeps the contents from spilling out. The smaller neck also slows evaporative loss better than a wider neck. The flat bottom of the conical flask makes it unlikely to tip over and spill.
Our large Erlenmyer Flasks are made from borosilicate glass, you can move it from a boil on your gas stove into a cold water bath for cooling, without the risk of cracking.
Our magnetic stirrers do not have electric heating elements
(We do not recommend the use of an electric element. If this cannot be avoided, we recommend using a larger pot as a hot water bath on the stove.) This means you can do the whole process in one container, keeping it simple and helping to reduce the risk of contamination when transferring from one container to another.
