Cooling/heating device

Abstract

A device is provided for cooling or heating vessels and containers for carrying out chemical or physical reactions. The device includes the following components in a vertical direction from top to bottom: a heat-conductive cooling or heating plate; at least one Peltier element equipped with electrical connections; optionally at least one heat-conductive separator plate between two Peltier elements respectively; a heat-conductive thermoblock, through which one or more fluid channels pass, for dissipation and supply of heat from and to the at least one Peltier element; and an external control unit for the at least one Peltier element. The components rest on top of one another and are therefore in direct planar contact with one another.
