At the same time, the internal and external are isolated to reduce the influence of the external environment on the culture environment and improve the stability of culture.

[0025] 2. A cooperation component is provided. The isolation net plate is sleeved inside the clamping limiting cover by magnetically attracting and fixing the connecting magnetic ring with the permanent magnet ring to realize the connection of the net plate, so that the equipment can be quickly replaced during isolation and protection. By rotating the connecting cooperation frame, the position of the counterweight is switched, and the connecting cooperation frame is magnetically attracted and clamped by the limiting magnetic ring. The counterweight is placed inside the connecting cooperation frame according to needs to realize counterweight processing and counterweight adjustment, so that the liquid level can be adjusted according to the flatness during microscope observation and culture, ensuring the stability of observation and culture during processing. By rotating the porous sealing ring, the air inlet and outlet size of the special-shaped air inlet hole is adjusted to realize the adjustment of air inlet and outlet and ensure the stability of air inlet and outlet. The liquid level of the culture dish is adjusted by using multiple groups of adjustment cooperation linkages to improve the stability of culture and the accuracy of observation.

[0026] In summary, through the mutual cooperation of the operation component and the cooperation component, and through the multi-position separation processing of the culture dish, the abnormal culture caused by excessive environmental changes can be reduced during the sampling observation and continuous culture processes. At the same time, through the counterweight adjustment and the isolation air inlet adjustment, the liquid level control and the culture environment control are realized, thereby effectively improving the stability of culture and the accuracy of observation.
