The main shapes are U-shaped and V-shaped, and the specifications include 96-well, 48-well, 24-well, 12-well, 6-well, etc. Different experiments require different specifications and shapes of cell culture plates. The specific choice depends on the type of cultured cells, the required culture volume and different experimental purposes.

[0003] For example, the Chinese patent number CN220166202U discloses a cell culture plate that is easy to assemble and disassemble. In this utility model, by providing a main culture plate and an auxiliary culture plate, different numbers and specifications of auxiliary culture plates can be selected according to actual needs for combination with the main culture plate. However, in this utility model, there are openings at the front and rear of the connection groove in the combination. Although this facilitates installation, it increases the risk of the culture plate slipping out, which can easily cause experimental damage. At the same time, the sealing structure is relatively bloated and cumbersome, which greatly increases the cost of use. Therefore, a detachable cell culture plate is proposed to solve the above problems. Utility Model Content

[0026] exist Figure 1 and Figure 2In the figure, dovetail blocks 405 are installed at the bottom of the seven auxiliary culture plates 2, and seven dovetail slots 406 are opened on the inner rear wall of the connecting groove 401. The dovetail blocks 406 are engaged with the dovetail slots 405, so that the auxiliary culture plates 2 cannot be separated from the bottom plate 1 by pulling up, pushing back, etc.

[0027] exist Figure 2 and Figure 3 In the figure, a transparent observation plate 407 is provided on the top of each of the seven auxiliary culture plates 2, a transparent rectangular frame 408 is installed on the bottom of each of the seven transparent observation plates 407, and a sealing ring 409 is provided on the outer surface of each of the seven transparent rectangular frames 408. The sealing ring 409 is used to increase the friction force to prevent the transparent rectangular frame 408 from separating from the auxiliary culture plate 2, thereby enhancing the connection stability and the sealing firmness.

[0028] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0029] When implementing, follow these steps:

[0030] 1) First, pull the baffle plate 403 upward to move in an arc, so that the opening of the dovetail slot 406 inside the connecting slot 401 is exposed;

[0031] 2) Then, the corresponding auxiliary culture plate 2 is pushed forward, driving the dovetail block 405 to move forward, so that the auxiliary culture plate 2 is separated from the bottom plate 1;

[0032] 3) Finally, pull up the transparent observation half 407 so that the transparent rectangular frame 408 drives the sealing ring 409 to separate from the auxiliary culture plate 2, thereby taking out the main culture plate 3.
