Description

Technical Field

[0001] The utility model relates to a culture device, in particular to a microorganism culture device. Background Art

[0002] Microbial culture refers to the rapid growth and reproduction of microorganisms with the help of artificially prepared culture media and artificially created culture conditions (including culture temperature, light, etc.). Temperature is the decisive factor for microbial growth. Only when the temperature is within a very narrow tolerance range above and below the optimal temperature can the most ideal and strong cell growth be achieved. In the prior art, incubators are often used to provide a suitable environment for the growth of microorganisms. Different microorganisms have different requirements for temperature and light. In the incubator, culture areas with different temperature and light conditions need to be divided according to the growth requirements of the microorganisms.

[0003] The prior art authorization announcement number is CN 219136764 U, which is a microorganism culture device. The microorganism culture device drives the rotating table and the culture dish to rotate by a motor, and then cooperates with the culture delivery head fixed on the top of the culture dish to infuse the nutrient solution into the culture dish, so that the nutrient solution does not need to be manually opened to replenish the device, which prevents the device from being easily contaminated by microorganisms in the air after opening, causing adverse effects on the cultured microbial community, and also saves time and labor, and does not require the staff to frequently add nutrient solution to the culture dish;

[0004] For the above-mentioned culture device, the culture dish is in a fixed position and cannot be raised or lowered to the incubator or raised for easy access. Secondly, the height of the culture dish cannot be adjusted for replenishing the nutrient solution, so that the dripping of liquid causes the microorganisms in the culture dish to splash out. Secondly, the above-mentioned nutrient solution has no manual control dosage, which reduces its practical effect. Utility Model Content
