Warburg apparatus

Warburg apparatus: A venerable device used in biochemistry for measuring brathing (respiration) by tissues. Tissue slices are enclosed in a chamber in which the temperature and pressure are monitored and the amount of gas produced or consumed by the tissue is measured. The Warburg apparatus was invented by the German biochemist Otto Heinrich Warburg (1883-1970), a pioneer in research on the respiration of cells and the metabolism of tumors. Warburg won the Nobel Prize in physiology or medicine in 1931.
