The Erlenmeyer flask: 153 years and counting

The Erlenmeyer flask (photo above by “Lucasbosch”) is much used by chemists everywhere. It was invented by the organic chemist Emil Erlenmeyer around 1860. The flask facilitates swirling or shaking, is spill-resistant, can be placed on a flat surface, and allows a stopper to be placed in the neck. A versatile piece of equipment: thanks, Emil!
