To determine the enthalpy of combustion of high-boiling-point, low-flammability liquids such as olive oil, they are burned in a pure oxygen atmosphere. The substances to be burned are placed in a small glass container, which is placed into the vertically arranged combustion lance, through which the oxygen is fed into the apparatus. The combustion lance is inserted into the hole of a rubber stopper, which is then positioned in such a way that the calorimeter vessel is tightly sealed at the bottom. This forces the hot combustion gases to flow through the calorimeter insert, thereby transferring their thermal energy to the calorimeter before they leave the apparatus through the opening at the top.
