PROBLEM TO BE SOLVED: To provide a container which can be insulated and heated at any temperature and can produce high heat-insulating effects. SOLUTION: A heater is mounted to the bottom of the container to directly heat the inner layers of the container, while a vacuum layer is mounted to the container so as to surround it, thereby effectively heating samples using low electric power. Further, since the heated samples are heat-insulated by the vacuum layer, twice effect is achieved that the samples are hard to cool down and can be easily heated.
