ABSTRACT:
A thermally insulated calorimeter includes a vessel with a chamber containing liquid nitrogen. The vessel is formed of four walls arranged proximately in parallel, each pair of adjacent walls delimiting a space. An inner wall forms the chamber, two partition walls are between the inner wall and an outer wall which is exposed to atmosphere. Each space contains a gas at atmospheric pressure. Each spacing is selected to minimize heat transfer from the atmosphere to the inner chamber, by establishing a maximum spacing for which the air is stagnant. A cover for the vessel has a set of walls with spacings similar to those of the vessel. Sealing for such spacing is provided for a removable main cover and a removable top cover for the calorimeter sample block.
