Centrifugal tube water bath heating device

The utility model discloses a centrifuge tube water bath heating device which comprises a heating pot, and a placing mechanism for placing a centrifuge tube, a stirring mechanism for stirring internal water flow and a heating mechanism for heating a solution in the heating pot are arranged in the heating pot. The centrifugal tube placing mechanism has the beneficial effects that when the placing mechanism is not placed in the heating pot, the sponge floating plate falls right above the fixed plate under the action of the elastic mechanism, then the centrifugal tube is mounted in the placing hole, and the mounted placing mechanism is placed in the heating pot filled with water, so that the centrifugal tube can be placed in the heating pot; and then a solution in the heating pot is heated through the heating mechanism, in the process of putting water, the sponge floating plate floats upwards under buoyancy, and the top cover covers the top of the sponge floating plate to form protection, so that the centrifugal
