Description

Technical Field

[0001] The utility model belongs to the technical field of experimental matching equipment, in particular to a water bath pot. Background Art

[0002] A water bath is a heating technique commonly used in laboratories that uses water as a heat transfer medium to achieve gentle and uniform heating of samples or reactants. Due to the high specific heat capacity of water, it can provide a stable temperature environment over a wide temperature range, usually not exceeding the boiling point of water. The main advantages of a water bath include high temperature control accuracy, gentle and uniform heating process, and easy and safe operation.

[0003] A water bath is a device that heats water in a bath. It is equipped with a heating element and a control system that can adjust the water temperature as needed. Modern water baths usually have a digital display and automatic temperature control function, which can accurately maintain the set temperature. Some advanced water baths also have functions such as programmable temperature curves, magnetic stirring and multiple heating holes to meet the needs of different experiments.

[0004] However, most water baths use trays to support the water bath container. If the buoyancy of the water is greater than the overall gravity of the water bath container, the water bath container will be unstable in the water bath and will float and move under the heat surge phenomenon generated by the heating of the water. In addition, using a tray to support the container in the water bath will affect the temperature transfer, because the tray itself can play a certain role in insulation, slowing down the heat exchange rate when the container is in direct contact with water, which will cause the heating time of the material inside the container to be slightly prolonged, and will cause the temperature of the water bath container in contact with the tray and the water to be inconsistent, thus affecting the accuracy of the experiment.
