Description

Technical Field

[0001] The utility model relates to the technical field of medical experiment, in particular to a multifunctional electrophoresis auxiliary device for medical laboratories. Background Technique

[0002] In medical laboratories, electrophoresis technology is often used. Electrophoresis refers to the movement of charged particles under the action of an electric field towards the electrode with the opposite electric charge. The technology that uses the different moving speeds of charged particles in an electric field to achieve separation is called electrophoresis technology. Through electrophoresis technology, the structure, function, and biosynthesis of biological macromolecules can be studied to clarify the essence of various life phenomena. When performing electrophoresis, an electrophoresis auxiliary device is required. However, the existing semiconductor wafer back polishing device still has some defects in the process of use;

[0003] For example, a multifunctional molecular biology electrophoresis auxiliary device proposed in the application number CN202022044213.8 includes a bottom plate. Legs are fixedly connected to the bottom of the bottom plate. A base is arranged at a position on one side above the bottom plate. A first vertical rod is fixedly connected vertically above the base. A chute is opened in the middle position on the horizontal side of the base. A spring is fixedly connected to the outer side of the first vertical rod. One end of the spring away from the first vertical rod is fixedly connected to a sliding seat. In the actual use process, this electrophoresis auxiliary device uses a fixing device to limit the position of the electrophoresis tank relative to the working bottom plate, thereby ensuring that the position of the electrophoresis tank relative to the working bottom plate will not shift during the electrophoresis process. However, the structure of this fixing device for positioning the electrophoresis tank is relatively complex and the operation is cumbersome. At the same time, when this electrophoresis auxiliary device is placed on an uneven tabletop, it is not convenient to perform horizontal adjustment, reducing the use effect.

[0004] Therefore, we propose a multifunctional electrophoresis auxiliary device for medical laboratories to solve the problems mentioned above. Content of the Utility Model
