The invention discloses a water bath in a laboratory and relates to the technical field of water baths. The water bath comprises a housing, wherein a circular plate is movably arranged at the top of the housing; a circular groove is formed in the center of the top of the circular plate; cylinders are fixedly mounted at the bottom of the circular plate and at two sides of the circular groove; a first spring is fixedly mounted on the side, away from the circular groove, of the inner chamber of each cylinder; a telescopic rod is fixedly mounted at the end, close to the circular groove, of each first spring; a first sector plate is fixedly mounted at the end, extending to the outside of each cylinder, of the corresponding telescopic rod; the tops of the first sector plates are connected with the bottom of the circular plate through connection blocks in a sliding manner; an arc-shaped cone block is fixedly mounted on the side, away from each telescopic rod, of the corresponding first sectorplate; the tops of the arc-shaped cone blocks penetrate the circular groove and extend to be above the circular groove; and a second sector plate is fixedly mounted at the bottom of each arc-shaped cone block. As the first arc-shaped plates and the arc-shaped cone blocks are arranged, after a test tube enters the housing, the size of an outlet is reduced as much as possible, and the temperature stability in the water bath is facilitated.
Description
technical field [0001] The invention belongs to the technical field of water baths, in particular to a laboratory water bath. Background technique [0002] A stainless steel tubular heater is placed horizontally in the constant temperature water bath. An aluminum shelf with holes is placed inside the sink. The upper cover is equipped with combined ferrules of different calibers, which can be adapted to flasks of different calibers. There is a drain pipe on the left side of the water bath. , The right side of the constant temperature water bath is the electrical box, and the front panel of the electrical box is equipped with a temperature control instrument and a power switch. [0003] Existing water baths often need to use extra tools to prevent the test tubes from falling when preventing the test tubes. At the same time, the opening of the water bath is often larger than the diameter of the test tube, which easily causes heat loss and causes the temperature of the water bat...
