<p>The device has a main body (110) tempered through two tempering units (200, 300) of which the first tempers the body in a first temperature range between two temperatures of which the first temperature is lower than the second and uses a first tempering fluid such as alcohol, whilst the second tempering unit (300) tempers the main body in a second temperature range between a third and fourth temperature where the third temperature is lower than the fourth and the second tempering unit is tempered by a second different fluid (320) such as air or nitrogen. The second temperature is lower than the fourth temperature. An electric tempering device (400) can be used which has a Peltier element formed as a flat dividing layer between the first and second tempering units.</p> |
