一种可重复使用可调节气体传质的细胞培养摇瓶盖
By designing an adjustable gas mass transfer cap for cell culture shakers, the problem of unadjustable vents in existing technologies has been solved. This enables gas exchange adjustment based on cell needs and convenient replacement of the filter membrane, thereby improving the stability and efficiency of cell culture.

AI Technical Summary
The caps of existing cell culture containers cannot adjust the size of the vent holes or the amount of airflow, and cannot be adjusted according to the different oxygen and carbon dioxide requirements of different cells.
An adjustable gas mass transfer cell culture shaker cap was designed. A knob drives a lead screw to rotate, and a slider slides under the limiting action of a limiting groove and a limiting block. A connecting rod pushes a sealing plate to slide along a slide rail to adjust the opening and closing of the vent holes. The filter membrane can be easily replaced through an annular frame.
This technology enables the regulation of oxygen and carbon dioxide gas transfer according to the different needs of cells, prevents contamination of the vents, and improves the stability and efficiency of the device.
