PROBLEM TO BE SOLVED: To prevent a vapor condensing into droplets on a sample container by outside air flowing into the storage from outside of the storage through a leak path.SOLUTION: The sample cooling device includes: a first heat transmission member arranged at a position coming into contact with a sample rack; a second heat transmission member for cooling the inside of a sample storage; and a dew-condensed water discharge mechanism for discharging dew-condensed water condensed on the second heat transmission member to the outside of the sample storage, in the sample storage for storing the sample rack. The sample storage has a structure whose internal space is not tightly sealed by the existence of an air leak path including at least a flow path between the inside and the outside, and includes an outside-air introduction part for forcibly blowing the outside-air into the internal space so that the pressure of the inside becomes higher than the pressure of the outside. An outside-air blowing port of the outside-air introduction part in the sample storage are set in its position and direction so that the outside air blowing into the storage directly heads for the second heat-transmission member. |
