PROBLEM TO BE SOLVED: To provide a thermal cycler and a control method for the thermal cycler, suitable for PCR including hot start.SOLUTION: There is provided a thermal cycler which comprises an attachment unit for attachment of a reaction container including a channel filled with a reaction solution and a solution having a different specific gravity from that of the reaction solution and being immiscible with the reaction solution, in which channel the reaction solution moves close to opposed inner walls; a first heating unit that heats a first region of the channel and a second heating unit that heats a second region of the channel, when the reaction container is attached to the attachment unit; a driving mechanism switching the arrangement of the attachment unit, the first heating unit and the second heating unit between a first arrangement and the second arrangement in which the lowest position of the channel is located within the first region and a second region, respectively; and a control unit controlling the driving mechanism, the first heating unit and the second heating unit, wherein the control unit controls the first heating unit to be a first temperature and the second heating unit to be a second temperature, and switches the second arrangement to the first arrangement when passing first time in the second arrangement and then passing second time in the second arrangement. |
