Warburg Apparatus
Warburg Apparatus (named for O. H. Warburg), an instrument (respirometer) for the determination of small quantities of gas at constant pressure and temperature; used in the investigation of processes that proceed with the liberation or absorption of gases—tissue respiration, fermentation, and individual fermentation reactions. The basic part of the Warburg apparatus consists of 12-14 small vessels that are hermetically connected to manometers by stopcocks; tissues or separate cell fractions that have been pulverized in a buffer-salt medium are placed in these vessels. The vessels are immersed in a water bath equipped with a heat-regulating device and a rocking mechanism. The quantity of gas liberated or absorbed is measured on a manometer. Warburg apparatus
War·burg ap·pa·ra·tus (vahr'bŭrg), a device for gauging the oxygen consumption and carbon dioxide production of incubated tissue slices by manometric measurement of changes in gas pressure produced by oxygen absorption in an enclosed flask. Synonym(s): Barcroft-Warburg apparatus [Otto H.

[Otto H. Warburg]Warburg apparatusA capillary manometer used for determining oxygen consumption and carbon dioxide production of small bits of cellular tissue. It is widely used in metabolism studies. See also: Warburg, Otto H.Warburg, Otto, German biochemist and Nobel laureate, 1883-1970.
