Abstract
Description
Technical Field
[0001] This invention relates to the technical field of cell culture, and more particularly to a culture plate that is easy to assemble. Background Technology
[0002] Currently, basic experimental cell culture plates on the market are available in 6-well, 12-well, 24-well, and 96-well sizes, with different well sizes. Typical design dimensions are: 9.6 cm² for a single well in a 6-well plate, 4.5 cm² for a 12-well plate, 2 cm² for a 24-well plate, and 0.32 cm² for a 96-well plate. Operators can choose different cell culture plates based on the number of cells to be seeded and the experimental groupings. Furthermore, for ease of handling and stacking in incubators, the outer shells of traditional 6-well, 12-well, 24-well, and 96-well cell culture plates are usually designed with the same size.
[0003] However, this design with the same shell size presents a significant waste problem. For example, if an experiment is grouped according to the number of cells to be cultured, and a 6-well plate is selected, but the total number of wells is not a multiple of 6, then the culture wells will be wasted. Utility Model Content
[0004] To address the problem of waste that often occurs with traditional cell culture plates in cell culture experiments, the purpose of this invention is to provide a culture plate that is easy to assemble and can reduce the waste of culture wells.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A culture plate that is easy to assemble includes a base plate 1 and a cover 2, the cover 2 covering the base plate 1, the base plate 1 having at least two culture wells 11; a locking block 12 is provided on the left side of the base plate 1, and a locking groove 13 is provided on the right side of the base plate 1, the locking block 12 on one culture plate being detachably connected to the locking groove 13 on other culture plates of the same or different specifications.
[0007] Furthermore, the cover 2 has annular protrusions 21 on the side facing the bottom plate 1, the same number as the culture holes 11. When the culture plate is in the closed state, the inner ring of each annular protrusion 21 abuts against the outer edge of a culture hole 11.
[0008] Furthermore, the base plate 1 includes a frame 14, a connecting plate 15, and a vessel 16. The connecting plate 15 is connected to the inner wall of the frame 14. The connecting plate 15 has multiple openings, and a vessel 16 is connected to the inner edge of each opening. Each vessel 16 is provided with a culture hole 11. The cover 2 is hinged to the rear side of the frame 14.
[0009] Furthermore, the base plate 1 is provided with two, three, twelve or thirty-two culture wells 11, and the multiple culture wells 11 located on the same base plate 1 are of the same size; the base plate 1 with two culture wells 11 is a two-well base plate, the base plate 1 with three culture wells 11 is a three-well base plate, the base plate 1 with twelve culture wells 11 is a twelve-well base plate, and the base plate 1 with thirty-two culture wells 11 is a thirty-two-well base plate.
[0010] Furthermore, the two culture wells 11 on the two-well base plate are arranged in a row.
[0011] Furthermore, the three culture wells 11 on the three-well base plate are arranged in a row.
[0012] Furthermore, the twelve culture wells 11 on the twelve-well base plate are arranged in a square matrix.
[0013] Furthermore, the thirty-two culture wells 11 on the thirty-two-well base plate are arranged in a square matrix.
[0014] Furthermore, the size of the culture well 11 in the two-well base plate is larger than that in the three-well base plate; the size of the culture well 11 in the three-well base plate is larger than that in the twelve-well base plate; and the size of the culture well 11 in the twelve-well base plate is larger than that in the thirty-two-well base plate.
[0015] Furthermore, the length of the base plate 1 of any two culture well plates of different specifications is equal.
[0016] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:
[0017] (1) This invention designs four specifications of culture plates: two-well, three-well, twelve-well, and thirty-two-well. The size of each culture well is consistent with the standard well size of traditional 6-well, 12-well, 24-well, and 96-well plates, respectively. Compared with traditional culture plates, this invention significantly improves experimental flexibility by reducing the total number of culture wells while maintaining an equivalent culture area. When the required sample size is not an integer multiple of the number of wells in a traditional plate, selecting a module with a lower number of wells can effectively reduce the idle rate of wells and avoid waste of consumables.
[0018] (2) This utility model adopts a modular combination design, which realizes the connection of cross-specification culture plates through standardized card blocks and card slot structures. Culture plates of the same or different specifications can be freely combined by plugging them in. This design ensures structural stability while facilitating handling and storage during the experiment, significantly improving the convenience of operation. Attached Figure Description

A locking block 12 is provided on the left side of the base plate 1, and a locking groove 13 is provided on the right side of the base plate 1. The locking block 12 on one culture plate can be detachably connected to the locking groove 13 on other culture plates of the same or different specifications.
[0031] Furthermore, in a preferred embodiment, the card block 12 is an elongated structure that matches the card slot 13. When connecting two culture well plates, the card block 12 can be inserted from the front or rear end of the card slot 13.
[0032] Furthermore, in a preferred embodiment, the card block 12 is a dovetail protrusion, and the card slot 13 is a dovetail groove.
[0033] Furthermore, in a preferred embodiment, the cover 2 has annular protrusions 21 on the side facing the base plate 1, the same number as the number of culture wells 11. When the culture well plate is in the closed state, the inner ring of each annular protrusion 21 abuts against the outer edge of a culture well 11. The annular protrusions 21 are used to seal the culture wells 11, preventing the culture medium from flowing out from the upper end of the culture wells 11 when the culture well plate is moved.
[0034] Furthermore, in a preferred embodiment, the base plate 1 includes a frame 14, a connecting plate 15, and a vessel 16. The connecting plate 15 is connected to the inner wall of the frame 14.

[0040] Furthermore, in a preferred embodiment, a limiting block is provided at one end of the slot 13. During connection, the locking block 12 of one culture plate is inserted from the other end of the slot 13 of the other culture plate. The end of the locking block 12 can abut against the limiting block. When it abuts against the limiting block, the front edges of the two culture plates are aligned, and the rear edges of the two culture plates are also aligned.
[0041] Furthermore, in a preferred embodiment, please refer to Figures 1 to 4 As shown, the base plate 1 is a two-hole base plate with two culture wells 11, and the two culture wells 11 are arranged in a row; further, the two culture wells 11 are distributed one after the other in the length direction;

[0046] Furthermore, in a preferred embodiment, please refer to Figure 8 As shown, the size of the culture well 11 in the two-well substrate is larger than that in the three-well substrate; the size of the culture well 11 in the three-well substrate is larger than that in the twelve-well substrate; the size of the culture well 11 in the twelve-well substrate is larger than that in the thirty-two-well substrate; the bottom surface area of a single culture well 11 in the two-well substrate is 9.6 cm², the bottom surface area of a single culture well 11 in the three-well substrate is 4.5 cm², the bottom surface area of a single culture well 11 in the twelve-well substrate is 2 cm², and the bottom surface area of a single culture well 11 in the thirty-two-well substrate is 0.32 cm².
[0047] Furthermore, in a preferred embodiment, the culture plate with a two-well base plate is a two-well culture plate, and the bottom surface of a single culture well 11 on the two-well culture plate is 9.6 cm²; the culture plate with a three-well base plate is a three-well culture plate, and the bottom surface of a single culture well 11 on the three-well culture plate is 4.5 cm²; the culture plate with a twelve-well base plate is a twelve-well culture plate, and the bottom surface of a single culture well 11 on the twelve-well culture plate is 2 cm²; the culture plate with a thirty-two-well base plate is a thirty-two-well culture plate, and the bottom surface of a single culture well 11 on the thirty-two-well culture plate is 0.32 cm².
[0048] Working principle:
[0049] For example, when an experiment requires two-well culture plates with a bottom area of 9.6 cm², if the required number of culture wells (11) is a multiple of 2, there will be no unused culture wells (11); otherwise, only one culture well (11) will be unused. For instance, if the experiment requires 9 culture wells (11) with a bottom area of 9.6 cm², 5 two-well culture plates can be used, leaving only one culture well (11) unused. If a traditional 6-well plate is used, two plates are required, resulting in 3 unused and wasted wells.
[0050] This invention reduces waste in the culture wells 11 while employing a modular design. Each culture well plate can be interconnected via clips 12 and slots 13, enabling convenient handling and flexible combination during experiments. When different numbers of wells are required, the connection can be freely expanded, significantly improving storage efficiency and operational convenience.
[0051] In addition to cell culture plates, culture dishes can also be used in cell culture experiments. For example, the bottom size of a traditional 6-well plate and a 35mm culture dish is the same, both being 0.3*10⁶. If the total number of wells required for the experiment is not a multiple of 6, 35mm culture dishes can be used instead. However, it is important to maintain consistency in all experimental conditions; either use 6-well plates exclusively or 35mm culture dishes exclusively. Using only 35mm culture dishes would significantly increase the number of dishes required for the experiment, making the operation cumbersome and inconvenient to handle, easily spilling the culture medium, and causing cells to tip over when placed in the incubator. On the other hand, using only traditional 6-well plates would waste culture wells.
[0052] This invention designs two-well, three-well, twelve-well, and thirty-two-well culture plates, with the size of each culture well (11) being consistent with the standard well sizes of traditional 6-well, 12-well, 24-well, and 96-well plates, respectively. Compared to traditional culture plates, this invention significantly improves experimental flexibility by reducing the total number of culture wells (11) while maintaining an equivalent culture area. When the required sample size is not an integer multiple of the number of wells in a traditional plate, selecting a module with a lower number of wells can effectively reduce the idle well rate and avoid waste of consumables. Furthermore, this invention is more convenient to operate than traditional petri dishes.
[0053] This invention adopts a modular design, using a combination of locking blocks 12 and locking slots 13 to connect culture plates of different specifications. Culture plates of the same or different specifications can be freely combined by plugging them in. This design ensures structural stability while facilitating handling and storage during experiments, significantly improving operational convenience.
[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
