[0002] Currently, in the process of medical analysis, it is often necessary to provide a constant temperature working environment for the binding reaction between samples and multiple reagents to ensure that the above binding reactions are not adversely affected by temperature changes. When conducting reaction tests on different samples or with different reagents, different containers need to be provided to prevent cross contamination between different samples or different reagents.

[0003] However, most of the methods currently available on the market use multiple reaction cups to contain samples and heat them by immersion in a water bath. However, the reaction cup must be cleaned every time a test is performed. On the one hand, if the reaction cup itself is not cleaned properly, it will have an adverse effect on subsequent use. On the other hand, it is easy to cause pollution and waste of the water bath. Once the water bath water is polluted, it will directly affect the detection process and cause deviations in the test results. In addition, it is not easy to operate multiple reaction cups at the same time. Utility Model Content
