However, since the electric heating tube is in direct contact with water, scale will be generated on the surface of the electric heating tube after long-term use, which not only affects the service life of the electric heating tube, but also increases the heating time of water. In addition, when the constant temperature water bath is used to heat samples in test tubes or beakers, it is not convenient to position and support the test tubes. When the hot water in the pot boils, the test tubes will shake, causing inconvenience in use. Utility Model Content
