Description

Biological reagent centrifuge Technical Field The utility model relates to the technical field of centrifuges, in particular to a biological reagent centrifuge. Background The centrifugal machine is used as a common material separation device, and the working principle of the centrifugal machine is that the material is rotated at a high speed, layering is realized by utilizing the density difference of different substances, the liquid with larger density is settled to the bottom layer, and the liquid with smaller density floats on the upper layer, so that the material separation is realized, and the required pure substances are obtained. Through retrieving, patent application number CN218167372U discloses a fixed stable biological reagent centrifugation device, although the device can be according to actual conditions free choice when using, can place single test tube, also can place a plurality of test tubes, has improved centrifugal efficiency, convenient to use, flexibility, and current device is equipped with heating mechanism generally and is used for carrying out heating operation to containers such as test tube, after the heating, the inside certain heat that can remain of device. When the reagent is placed again, these residual temperatures will directly act on the newly placed reagent. For those reagents that do not require heating, such accidental heating may adversely affect the quality of the centrifuged reagents, interfering with the experimental results or product quality. Furthermore, after the test tube is placed, the test tube is inside the centrifugal mechanism, which makes the process of taking out the test tube rather inconvenient, reducing the operating efficiency. Therefore, the existing centrifuges still need to be further optimized and perfected in design to overcome the defects in these practical applications. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a biological reagent centrifuge, which solves the problems in the background technology.
