According to the automatic preservation / extraction control device for the frozen cells, the quality of the frozen cells can be guaranteed, and the efficiency of preservation / extraction of the frozen cells is increased.

Description

technical field [0001] The present invention relates to the technical field of liquid nitrogen storage, cell storage, mechanical movement at ultra-low temperature and heat preservation and sealing technology, in particular to a versatile ultra-low temperature automatic access control device for frozen cells. Background technique [0002] With the development of science, biological research has already entered the level of cells and even molecules from the overall study of biological organisms. Cell biology takes cells as the research object, and studies the structure and function of cells and organelles, the life history of cells and the laws of various life activities from three levels: the overall level of cells, the submicroscopic level, and the molecular level. Cell biology is one of the important pillars and core disciplines of modern life sciences, and it is also a frontier branch of life science research. Cell biology bridges the gap between the molecule and the whol...
