Abstract

The invention discloses a stable water-bath heating device. The stable water-bath heating device comprises a water-bath trough; the water-bath trough comprises a trough body, the trough body is provided with a cover plate, the edge of the cover plate is provided with a lug boss, a lug boss groove matched with the lug boss is arranged at a junction of the water-bath trough and the cover plate, and the lug boss groove is provided with a sealing ring; and the cover plate is provided with a plurality of test tube racks, the test tube rack comprises a settlement hole, the settlement hole is provided with a conical cylinder, the conical cylinder is perpendicular to the lower surface of the settlement hole, and the conical degree of the conical cylinder is 1: 2.2. The stable water-bath heating device has the advantages that the defects of the prior art can be overcome, and the structure design is reasonable and novel.

Description

technical field [0001] The invention relates to a stable water bath heating device, which belongs to the field of teaching equipment. Background technique [0002] Fill a large container with water first, then place the container to be heated into the container where the water was added. Heating a large container of water is achieved by heating the water in the large container and then transferring heat (heat transfer) through the water to the container that needs to be heated to achieve the purpose of heating. Because at one standard atmospheric pressure and water without any impurities, the condition for water to reach the boiling point is 100 degrees Celsius, but it needs to absorb more heat to change from liquid to gas. In the water bath method, the water in the beaker can only have a temperature of 100 degrees Celsius before it turns into water vapor, which cannot provide more heat for the water in the test tube, so the liquid in the test tube cannot boil. Therefore, ...
