When taking in outside air with a fan to control the temperature inside a covered portion where a specimen is installed, the internal temperature may change depending on an environment temperature to cause a difference in temperature control. The wind generated by the fan may blow against a reaction container depending on its loading position and it may influence the temperature control over individual specimens and lead to problems with temperature accuracy, temperature rise speed, and temperature drop speed A reaction container avoiding these problems has a covered portion which performs temperature control on the reaction container and in which a cover and a fin cover have a heat insulating structure. A heat source is provided for controlling an internal temperature of an internal covered space. The internal temperature is kept constant and the influence of the environment temperature over the temperature control of the reaction container is minimized. |
