| 1. A device for the adjustment of a temperature of a liquid which is contained in one or more sample vessels, the device comprising:
a transport unit effective to hold and transport the sample vessels,
magnetic particles added to the liquid in the one or more sample vessels;
one or more temperature sensor elements effective to sense temperature of the liquid in the one or more vessels;
a temperature adjustment unit effective to act on the liquid contained in the one or more sample vessels;
a control unit being operationally connected to the temperature adjustment unit and the one or more temperature sensor elements,
wherein the liquid to be analyzed contains said magnetic particles in order to accelerate the temperature adjustment in the
liquid to be analyzed, the magnetic particles having a heat conductivity that is greater than 0.6 W/m K.
