A stirring hot plate (20) having an electrical heating element (30) embedded in a generally horizontal plate (26) for supporting a vessel containing a substance to be selectively heated and stirred. The stirring hot plate (20) has a high temperature enclosure (84) mounted to the bottom of the plate (26) that receives the ends (32, 33) of the electrical heating element (30). A stirring device drive (64) and control (68) are mounted in a low temperature enclosure (86). A tubular conduit (96) has one end (107) connected to the low temperature enclosure (86), and an opposite end (98) connected to the high temperature enclosures (84). The tubular conduit (96) has an internal passage (97) for receiving and carrying wires (76, 80, 83) between the high and the low temperature enclosures (84, 86). The tubular conduit (96) is made of a material having a low thermal conductivity to maintain the one end (107) of the conduit (96) at a temperature substantially lower than the opposite end (98) having a temperature approximately equal to the temperature of the plate (26).

[ What is claimed is:] [1.] A stirring hot plate comprising:a plate having a generally horizontal upper surface for supporting a vessel containing a substance to be heated and stirred;an electrical heating element in a heat transfer relation to the vessel supported on the plate, the heating element electrically connected to heat the substance in the vessel supported on the plate;a high temperature enclosure disposed on a lower surface of the plate for receiving an end of the electrical heating element, the high temperature enclosure having a temperature approximately equal to the temperature of the plate when the heating element is electrically energized;a low temperature enclosure having a desired temperature lower than the plate;a stirring device for stirring the substance in the vessel, the stirring device including a stirring device control mounted in the low temperature enclosure; anda tubular conduit havingone end connected to the low temperature enclosure, andan opposite end connected to the high temperature chamber,the tubular conduit being made of a material having a low thermal conductivity such that the one end of the conduit does not exceed the desired temperature in response to the opposite end of the conduit being approximately equal to the temperature of the plate.
