Abstract:
1. A differential scanning calorimeter, comprising: a heat sink, which stores a measuring sample and a reference material; a heater, which heats the heat sink; a cooling block, which is separated away from the heat sink, and is positioned below the heat sink; a thermal resistor, which is connected between the heat sink and the cooling block, and forms a heat flow path therebetween; a cooling head, which is provided with an inner hole for allowing the cooling head to be detachably fitted to the cooling block, and is cooled by an external cooling device; and differential heat flow detectors, which output a temperature difference between the measuring sample and the reference material as a heat-flow-difference signal, wherein: the cooling block has a side wall, which is formed on an outside of a connected portion connected to the thermal resistor, and is fitted to the inner hole; and the cooling head is arranged so that an upper surface thereof is positioned flush with or below the connected portion.
