Erlenmeyer flask
Erlenmeyer Flask
The Erlenmeyer Flask (pronunciation: /ˈɜːrlənˌmaɪər/), also known as a conical flask or titration flask, is a type of laboratory glassware invented by the German chemist Emil Erlenmeyer in 1860.
Etymology
The Erlenmeyer Flask is named after its inventor, Emil Erlenmeyer, a German chemist who designed this piece of laboratory equipment in 1860. The term "flask" comes from the Old English word 'flasce' which means 'bottle', and it has been used in scientific contexts since the late 14th century.
Description
An Erlenmeyer Flask is a conical shaped flask with a flat base and a cylindrical neck. It is used in laboratories for titration, as the narrow neck allows the user to control the amount of liquid being added to the flask. The conical shape also makes it easier to swirl the liquid inside the flask without risk of spillage.
