Abstract
The invention relates to a thermocycler module for heating and/or cooling of a thermocycling device comprising a thermal switch, a heating block and a heat sink. The thermal switch comprises a thermoconducting liquid, e.g. a magnetic fluid or a liquid metal, and a stimulating unit, e.g. a magnetic unit or a Lorentz-force unit, for moving the thermoconducting liquid. The movement of the thermoconducting liquid provides, in an on-state of the thermal switch, a thermal connection between the heating block and the heat sink.
