Manometer and reaction vessels, “Warburg Apparatus“

Manometers are devices that can be used to measure the pressure of a gas.

In the 1920s, Otto Warburg and Erwin Negelein combined them with vessels in which biochemical reactions took place. They succeeded in determining aspects of the gas metabolism of tissues and cells – such as how much oxygen was consumed in a reaction, or how much carbon dioxide was produced. This manometric device is known as the Warburg apparatus.
