Abstract
A heated cover for a receptacle containing a vaporizable substance. The cover is heated to a temperature above the temperature of the substance so as to prevent condensation of vapor evaporated from the substance. A device for placing and removing the cover with respect to the receptacle is designed in connection with a temperature-controlled heating/cooling plate which controls the temperature of the contents of the receptacle.
