Description

Technical Field

[0001] The utility model relates to the technical field of cell culture, in particular to a cell culture dish. Background Art

[0002] A petri dish is a laboratory dish used for microbial or cell culture. It consists of a flat disc-shaped bottom and a cover, and is generally made of glass or plastic. There are basically two types of petri dishes, mainly plastic and glass. Glass can be used for plant materials, microbial culture, and animal cell adherent culture. Plastic may be made of polyethylene, and there are disposable and reusable ones. They are suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the culture of plant materials.

[0003] In the process of realizing the present invention, the inventors found that the prior art had the following problems: during the cell culture process, the tissue block needs to be placed in the culture solution. However, due to the influence of buoyancy, the tissue block may float out of the culture solution, so that the tissue block cannot be completely immersed in the tissue solution, thereby affecting the cell culture effect. Secondly, the existing culture dishes are very inconvenient to take when in use due to their small size, and they often fall and cause damage to the culture dishes, which directly affects the efficiency of cell production and causes certain losses. Therefore, we propose a culture dish for cell production. Some culture dishes cannot adjust the aerobic or anaerobic environment and lack functionality. Utility Model Content
