Description

Technical Field

[0001] The present application belongs to the technical field of medical or biological experimental equipment and instruments, and in particular relates to a fully enclosed bacterial inoculation and streak collection cup and culture dish kit. Background Art

[0002] Petri dishes are essential laboratory instruments in fields such as medical testing and biological cultivation. They are primarily used to create a relatively stable and suitable culture environment while isolating the internal and external environments, preventing external interference and leaking the cultured material. Currently, commonly used petri dishes (Petri dishes) are generally made of polymer or inorganic materials. Their basic structure consists of a petri dish body and a lid. However, due to the need for sampling and streaking operations during the culture process, the petri dish often needs to be opened for these operations. Consequently, the sealing performance of the petri dish is relatively poor. The sealing performance during the experiment is primarily guaranteed by the external sterile operating environment. However, during the sample inoculation and culture streaking processes, the petri dish inevitably needs to be opened and comes into contact with external sample collection and streaking devices. Therefore, the internal closed environment cannot be guaranteed, which often leads to instability and disturbance of the internal culture environment. Since these instabilities and disturbances are often caused by tiny microorganisms or dust impurities, they are extremely difficult to detect with the naked eye. Moreover, the changes in the internal environment after the experiment are not always obvious. Therefore, they cause great instability in the culture and experimental process, results, and data, and may even lead to completely erroneous results. Summary of the Invention
