This application discloses a circulating carbon dioxide incubator, belonging to the field of biological culture equipment technology. It includes an incubator body, an exhaust pipe, and an intake pipe. A limiting seat is fixed inside the incubator body, and a placement plate slides within the limiting seat. An exhaust box is fixed through the front end of the incubator body, and a first vent hole is opened on the exhaust box in the front area of ​​the lower placement plate. This circulating carbon dioxide incubator, by changing the traditional bottom humidification method, sets up humidification boxes inside the exhaust box and the conversion box. The positions of the humidification boxes correspond to the areas of different placement plates. A fan drives airflow circulation, allowing the moisture generated by the humidification boxes to be evenly distributed to all levels of the incubator. This solves the problem of uneven humidity distribution between different levels within the incubator, reduces dehydration of upper-layer samples and mold growth in lower-layer samples due to excessive humidity, and improves the biological sample culture effect.

The application discloses a microscope living body culture environment control system and method, relates to the monitoring control technical field, can be applied to the microscopic observation demand in the field of cell biology and medicine, and mainly solves the problem of heating and airflow disturbance interference micro-imaging of the existing microscope living body sample culture device. Mainly includes embedded controller, monitoring component, temperature control component and gas control component; wherein, the embedded controller determines real-time temperature monitoring data and real-time concentration of target gas based on real-time temperature sensing signal and gas concentration sensing signal; calculates temperature deviation and gas concentration deviation; when the temperature deviation and / or gas concentration deviation does not satisfy the corresponding target parameter deviation condition, determines the target control component and the control signal of the target control component according to the deviation that does not satisfy the target parameter deviation condition; the control signal is sent to the target control component. The application is mainly used for controlling the environmental parameters of living cells under microscope observation.

By placing sample culture dish on conveying component, and guiding it by sequencing component, so that it is neatly sorted, subsequently by pushing component, the sample culture dish neatly sorted on conveying component is pushed to rotating stacking component one by one and is stacked, so that it is vertically stacked one by one, realize automatic sorting and arranging of sample culture dish, reduce manual operation, improve efficiency.

This invention provides a microbial sample culture and detection device, including a main control console, several sample boxes, and an optical monitoring component. The sample boxes are stacked sequentially from bottom to top on the main control console, with lifting channels connecting the sample boxes to the top of the main control console. The optical monitoring component includes an optical sensor and a lifting mechanism. The lifting mechanism has a movable end that moves along the lifting channel, and the optical sensor is mounted on the movable end of the lifting mechanism to move up and down with it. This invention features a separate main control console and sample boxes design, allowing multiple sample boxes to be stacked for sample culture and detection as needed. This modular design facilitates expansion of the sample box capacity. Furthermore, scanning is performed before and after adding or removing sample boxes using an optical monitoring component that can move within each sample box, resulting in low expansion costs.

This invention discloses an experimental sample culture device based on cell biology, relating to the field of culture dish technology. It includes a culture section, with a supplementary lighting support at the bottom for providing supplementary lighting to the culture section. A culture medium pusher is mounted on the supplementary lighting support and connected to the bottom of the culture section. Delayed limiting components are mounted on both sides of the supplementary lighting support to stop the culture section. A cover fastener is mounted on the culture section. The use of the culture medium pusher in conjunction with the height-adjustable culture section allows for rapid isolation of the culture medium when observing cultured cell tissues within the culture dish, thus solving the problem that current culture devices are not convenient for rapid culture medium separation and that manual observation time is difficult to control during microscopic observation.

This utility model relates to the field of culture medium sampling technology, specifically to a sampling device for culture medium processing, including a base plate and a sampling assembly. The sampling assembly includes two support frames, a support plate, an air pump, and multiple sampling structures. The two support frames are spaced apart on the base plate, and both ends of the support plate are fixedly connected to the two support frames respectively. The air pump is located above the support plate. The sampling structures include an installation cylinder, a sampling cylinder, a rubber stopper, and a connecting tube. The installation cylinder is threadedly connected to the support plate and passes through the support plate. The sampling cylinder is detachably connected to the installation cylinder and the rubber stopper is detachably connected to the sampling cylinder. One end of the connecting tube is connected to the rubber stopper, and the other end of the connecting tube is connected to the output end of the air pump. When sampling culture medium samples at different depths, it is not necessary to change sampling needles of different lengths; the depth of the sampling cylinder in the culture medium can be adjusted directly through the installation cylinder. The operation is simple and highly practical.
