A petri dish box

Abstract

The invention relates to the field of bioexperiment instrument equipment, in particular to a culture dish box. The culture dish box comprises a box cover, a base and a culture dish rack, wherein the box cover is cylindrical and hollow inside, the top end of the box cover is sealed, threads are arranged at the lower end of the inner surface of the side wall, and ventilation switches are arranged in the middle of the side wall; the base is a solid cylinder, threads are arranged at the upper end of the side surface, insertion holes are formed in the top end of the base and reach the 3 / 4 height of the base instead of penetrating through the whole base, the threads at the upper end of the side surface of the base correspond to the threads at the lower end of the inner surface of the side wall of the box cover, and the box cover is opened and closed through threads; the culture disk rack comprises pillars and more than one tray, the pillars and the trays are integrated and cannot be detached, the pillars are correspondingly inserted into the insertion holes in the base, and the culture dish rack is fixed on the base through the pillars and is detachable. The culture dish box provides private space for sterilization of a culture dish, solidification of a culture medium flat plate and culture of special microorganisms, and the contamination rate of the microorganisms in the whole inoculation and culture process can be reduced.

Description

technical field [0001] The invention relates to the field of biological experiment equipment, in particular to a petri dish box. Background technique [0002] Petri dishes are glass experimental equipment often used in microbiology laboratories, mainly used to cultivate various microorganisms. Usually, the process of microbial inoculation and cultivation is as follows: (1) wash and dry the petri dish, wrap it in newspaper, and sterilize it in a pressure cooker; The quantity is limited, so other people can use it at will during the solidification process of the plate); (3) inoculate; (4) put the inoculated culture dish into a disposable fresh-keeping bag; (5) transfer it to the incubator for cultivation (because The number of laboratory incubators is limited, so various microorganisms are cultivated together, and others can open the incubator arbitrarily during the cultivation period). There are obvious defects in the above whole operation process: (1) There is no fixed con...

AI Technical Summary

Problems solved by technology

There are obvious defects in the above whole operation process: (1) There is no fixed container for the sterilization of the petri dish, and it can only be wrapped in newspaper, which is not only time-consuming and laborious, but also easy to enter water during the sterilization process, causing the petri dish to scatter and the sterilization is not complete; (2) It is easy to be infected with bacteria during the solidification process of the poured medium plate; (3) the disposable fresh-keeping bag is not only wasteful but also airtight, which is not conducive to the growth of aerobic bacteria; (4) it is not only easy to cultivate various microorganisms in the incubator together Infection, and aerobic and anaerobic conditions cannot be achieved
