Description

Technical Field

[0001] The utility model belongs to the field of bacterial culture dishes, in particular to a bacterial culture dish with a partitioning function. Background Art

[0002] A petri dish is a laboratory vessel used for microbial or cell culture. It consists of a flat, disc-shaped base and a lid, and is generally made of glass or plastic. Petri dishes are generally divided into two categories: plastic and glass. Glass dishes can be used for plant materials, microbial culture, and adherent culture of animal cells. Plastic dishes may be made of polyethylene and are available in both disposable and reusable formats. They are suitable for laboratory inoculation, streaking, and bacterial isolation, and can be used for culturing plant materials.

[0003] According to a Chinese patent with the announcement number "CN219032121U", a bacterial culture dish with a partitioning function is disclosed, including a bacterial culture dish main body, the inner cavity of which is provided with a partitioning component, the partitioning component can not only ensure that the bacterial culture dish main body has the partitioning function, but also facilitate the internal partitioning application of the bacterial culture dish main body and has high flexibility. The bacterial culture dish main body includes a culture dish base, the interior of the culture dish base is movably connected to the culture dish shell, the outer surface of the culture dish shell is movably connected to the culture dish cover, the top of the culture dish base is provided with an annular groove, the inner bottom wall of the inner cavity of the annular groove is movably connected to a sealing ring, the inner cavity of the annular groove is movably connected to the culture dish shell, and the sealing ring is movably connected to the culture dish shell. The utility model not only ensures that the bacterial culture dish main body has the partitioning function, but also facilitates the internal partitioning application of the bacterial culture dish main body and has high flexibility;

[0004] It can be seen from the above structure that by clamping the culture dish shell into the inner cavity of the annular groove and making close contact with the sealing ring, and then threading the threaded bolt into the inner cavity of the threaded hole, and then clamping the clamping protrusion into the inner cavity of the clamping groove as needed, the dividing plate is tightly clamped with the outer surface of the mounting rod and the inner cavity of the culture dish shell, that is, the main body of the bacterial culture dish is divided into several areas, thereby ensuring that the main body of the bacterial culture dish has a partitioning function. However, it can be seen from the above figures and texts that the sealing between the main body of the bacterial culture dish and the partitioning component is not good during use, which is likely to cause a mixture of multiple bacteria when different bacteria are cultured, thereby leading to the failure of bacterial culture. For this reason, a bacterial culture dish with good sealing and partitioning function is proposed. Utility Model Content
