THERMOCYCLING DEVICE HAVING THERMOCYCLER MODULE WITH THERMAL SWITCH, METHOD OF COOLING HEATING BLOCK IN THERMOCYCLER MODULE OF THERMOCYCLING DEVICE AND ANALYTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thermocycling device having a thermocycler module capable of rapidly allowing heating stage and cooling stage with a sure and highly reproducible manner.;SOLUTION: A thermocycler module (10) for heating and/or cooling in a thermocycling device includes a thermal switch (16), a heating block (12) and a heat sink (14). The thermal switch (16) includes a thermoconducting liquid (68), e.g. a magnetic fluid (70) or a liquid metal, and a stimulating unit (64), e.g. a magnetic unit (66) or a Lorentz-force unit, for moving the thermoconducting liquid (68). The movement of the thermoconducting liquid (68) provides, in an on-state of the thermal switch (16), a thermal connection between the heating block (12) and the heat sink (14).;COPYRIGHT: (C)2010,JPO&INPIT
