効率良く熱伝導を行うことができる。When the liquid heat medium 5 is poured in this way, the granules 4 farther from the heater 1 are also uniformly and accurately heated by heat conduction due to convection of the heat medium 5,
In addition, the spherical granules 4 further facilitate slipping of the sample container 3 by further increasing slip and fluidity due to the liquid heat medium 5, and are evenly adhered to the entire peripheral surface of the container 3 after being inserted. The floating of the container 3 due to the buoyancy and falling of the container 3 are prevented. The granules 4 and the sample container 3
The liquid heat medium 5 is in close contact with the gap therebetween, so that heat can be efficiently conducted to the entire circumference of the container 3.
