Abstract

Thermostatting device for adjusting the temperature of a sample to any vas within a predetermined temperature range, comprising a main body (12) of good heat-conducting properties which has its first end thermally connected to a first thermostat (14) and its second end thermally connected to a second thermostat (16) that can be set to a temperature different from that of the first thermostat, the main body (12) being sized in such a way that a temperature gradient develops along the main body (12) between these ends, and comprising a sample holder body (22) arranged on the main body (12) for being thermally coupled with the latter at any point between the ends of the main body.
