<p>Disclosed is a heating apparatus for distillation, that enables highly precise temperature control and improves temperature distribution precision. A heating apparatus for distillation 1 is equipped with a closed-end, cylindrical heater tube 20 that has an opening to allow insertion of a sample tube 10, to distill a sample in the sample tube 10 by heating the sample tube 10 with the heater tube 20. The heater tube 20 is equipped with a closed-end, cylindrical heater-tube body 22 formed with a round-shaped portion 22c in a round-shaped cross section, that contracts toward a bottom surface 22b near the bottom surface 22b on a circumference thereof; a heater layer 24 that covers an outer circumference of the heater-tube body 22 extending from a side end, or near an opening 22a of the heater-tube body 22 to the round-shaped portion 22c; and a pair of belt-shaped electrodes 25, 26 established from a bottom-surface side end portion 24a of the heater layer 24, or from near that across to a side-end portion of the opening 22a in the heater-tube body 22 or near that, to heat the heater layer 24 by energizing the pair of electrodes 25, 26.</p> |
