A container used to quantitatively absorb carbon dioxide in organic elemental analysis. Carbon dioxide produced by burning organic compounds is quantitatively absorbed in a potassium hydroxide sphere containing a 30-50% potassium hydroxide solution. A chemical balance is used to measure the weight of carbon dioxide in the sphere and determine the carbon content. Various shapes have been devised, the most common being the Winkler potassium hydroxide sphere, the Geissler potassium hydroxide sphere, the Liebig potassium hydroxide sphere, and the Wanderburg potassium hydroxide sphere.
