Erlenmeyer flasks

In the laboratory

• For mixing liquids
• Accelerating dissolution processes by swirling or stirring
• Suitable for use with magnetic stirrers

Misappropriated Uses

• As a cork-stoppered, decorative, and hygienic dispenser for peanuts at aperitifs
• As a water or wine carafe
• As a flower vase (see also Useful information)

The Erlenmeyer flask was developed in 1860 by the German chemist Emil Erlenmeyer. Its neck narrows toward the top, reducing the risk of contents escaping uncontrollably when adding liquids or during swirling, stirring, or boiling. Erlenmeyer flasks are also suitable for use with magnetic stirrers.

Tip for Using the Erlenmeyer Flask as a Flower Vase:

Did you know that cut flowers last longer with a copper coin in the water? In the Middle Ages, it was known that water in silver or copper vessels stayed fresh longer, and bacterially contaminated water became drinkable again. Copper and silver ions, with antibacterial properties, reduce bacterial growth, helping to preserve the water and keep cut flowers fresh. A sufficient amount of copper ions dissolve from the coin in the water to produce this bactericidal effect.
