Abstract: A temperature control element for a measuring device for controlling the temperature of a measurement sample, comprising first and second heating elements delivering thermal energy to the measurement sample, and control means for controlling the heating of the measurement sample, wherein the first and second heating elements heat the measurement sample until a limit temperature has been reached, and wherein thermal resistivity between the first and second heating elements is increased starting at the limit temperature, and the control means disconnects the contact between the first and second heating elements when the limit temperature is reached. A cooling element withdraws thermal energy, and the control means controls cooling of the measurement sample, wherein thermal energy is withdrawn from measurement sample by bringing the cooling element closer to the shut-off of the first heating element, and interrupting the contact between the cooling element and the shut-off of the first heating element.

Abstract: A device for recording the boiling curve of liquids, in particular petroleum products, made of a distillation apparatus which includes a distillation column and a condenser, a sample dish connected to the distillation apparatus and a pump connected to the sample dish to fill the sample dish, wherein the filling means and the condenser are made of well heat-conducting material and the filling means and the condenser are connected to a temperature controller.

Abstract: Described is a method for recording the boiling curve of liquids, in particular petroleum products and/or solvents, in which a sample amount of the liquid to be analyzed is evaporated and subsequently condensed, wherein the vapor temperature and the respectively evaporated amount of liquid are monitored, the sample amount is dosed by a a pump, for example, wherein the pump and the condensate collection chamber are brought to a defined, and preferably identical, temperature level. The condensed volume is determined volumetrically and the distillation residue of the sample amount is determined by weighing.
