Abstract

The invention discloses a test tube preheating device. The test tube preheating device comprises a preheating box, wherein the interior of the preheating box is fixedly connected with a cushion plate;the top part of the cushion plate is fixedly connected with a separating plate; the top part of the cushion plate is movably connected with a test tube body; the surface of the separating plate is provided with an opening which is positioned at the bottom part of the test tube body; the top end of the test tube body extends out of the exterior of the preheating box; the interior of the preheatingbox is fixedly connected with an electric heating wire at the bottom part of the cushion plate and a heat insulation plate; the heat insulation plate is positioned at the bottom part of the electricheating wire. The test tube preheating device has the advantage that the air in the preheating box is heated by the electric heating wire at the bottom part of the test tube body, a motor is used fordriving fan blades to rotate so as to blow the heated air into the test tube body, all test tubes in the preheating box can be quickly heated, and the respective heating is not needed, so that the test tube preheating time is shortened, the working efficiency of test is indirectly improved, and the test tube preheating device is suitable for people to use.

Description

technical field [0001] The invention relates to the technical field of chemistry teaching, in particular to a test tube preheating device. Background technique [0002] Test tube, a commonly used instrument in chemical laboratories, is used as a reaction container for a small amount of reagents. The test tube is generally made of oil glass, and the test tube needs to be preheated before heating to prevent the test tube from being broken due to the large temperature difference during heating. [0003] The existing way to preheat the test tube is to burn the test tube on the outer flame of the alcohol lamp. This preheating method can only preheat one test tube at a time. The test tube is preheated, and such a preheating method will prolong the test time, affect the work efficiency of the test, and be inconvenient for people to use. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention pr...
