Title: Sample cooling apparatus and methods

Abstract: A sample cooler has a thermostatic chamber containing a heat-conducting block on which vessels containing liquid samples are set. A control unit activates a cooling mechanism of the air cooling type to cool the air inside the thermostatic chamber. Thereafter, when the temperature or humidity inside the thermostatic chamber is detected to have reached a specified level, when condensation of dew is detected inside the thermostatic chamber, or when a predetermined time has elapsed, the control unit starts to operate another cooling mechanism of the direct cooling type to cool the heat-conducting block, such that the samples can be cooled directly and quickly under a dehumidified condition without causing dew condensation.
