[0002] The water bath constant temperature oscillator is a multifunctional laboratory equipment. It is mainly used to maintain a stable temperature of the sample and keep the sample at a constant temperature during the experiment. By oscillating or shaking, the water bath constant temperature oscillator can fully mix and dissolve the sample. In cell culture experiments, it can provide a mild environment to promote cell growth and keep the cells healthy. The water bath constant temperature oscillator can be used not only to oscillate reagent bottles, but also to oscillate microplates. Microplates are a kind of transparent plastic plate specially used for placing samples. The wells are used to place samples to be tested or samples that need to be oscillated and cultured.

[0003] When the existing water bath thermostatic oscillator is used with a microplate, the function of the water bath thermostatic oscillator is to place samples. The existing thermostatic water bath oscillator usually fixes the samples by a spring rope, which cannot be reused because the spring rope will be deformed when it is repeatedly stretched and contracted, thereby deteriorating the fixing effect.
