[0004] In experiments, it is often necessary to heat the test tube to heat the liquid in the test tube, but the wall thickness of the above-mentioned prior art is uniform, the heating is slow, and the heating efficiency is low. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a new type of test tube to solve the problems of uniform wall thickness, slow heating and low heating efficiency in the above-mentioned prior art.

[0025] The utility model provides a technical solution, in which liquid is injected into a glass test tube 110 through an opening at one end of the cylindrical portion 110. When heating is required, a thin plate 520 on the semicircular portion 120 is fixed next to a fire source, so that the fire source heats the thin plate 520. Since the thickness of the thin plate 520 is less than the thickness of any outer wall of the glass test tube 100, the thin plate 520 is more easily heated, thereby facilitating heating of the liquid inside the glass test tube 100. Compared with the prior art mentioned in this document, the present solution saves heating time and improves heating efficiency.
