Description
Technical Field
[0001] The utility model relates to the technical field of cell culture, in particular to a cell culture dish rack. 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 adherent culture of animal cells. 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] However, the current cell culture dish rack has a relatively single function. It can only support the culture dishes and cannot perform layered control operations on the culture dishes. Experimenters are often required to operate different culture dishes one by one, which makes the experimental process cumbersome. During the operation, the culture dishes are often exposed to the air, and bacteria in the air enter the culture dishes, resulting in inaccurate experimental results. Therefore, we proposed a culture dish rack with a layered function and capable of performing experimental operations on culture dishes in a sterile environment to solve the above problems.
