Abstract: A nucleic acid amplifier comprises a holder 3 which is provided with a plurality of temperature control blocks 10 each designed to hold at least one reaction vessel 105 storing a reaction solution. The temperature of the reaction solution in each reaction vessel 105 is controlled individually by using temperature control devices 14 and 15 arranged in each of the temperature control blocks 10. The temperature that is set in each temperature control block 10 and the timing for temperature changes are controlled independently of the temperatures of other temperature control blocks 10.

Abstract: 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.
