Since water was used as the heat medium, the sample container comes into contact with water. Moreover, it was impossible to rapidly raise and lower the temperature of the sample. It took a long time to reach a certain temperature, and when the set temperature was changed, the response speed was slow. Further, there has been no one having a structure of an observation through hole for optical measurement of a cooled object while controlling a precise temperature program.
