The invention belongs to the technical field of cell sorting, and concretely discloses a magnetic cell sorting apparatus based on nanoferritin adsorption. The sorting apparatus comprises nanoferritin particles and a laminar aseptic sealed chamber, and a sample bottle, and a cell sorting tank having a magnetic field, a nano-iron particle eluting device, a multi-cell automatic culturing system, a recovering, rinsing and loading device, a control system for controlling the temperature, humidity and air cleanliness in the sealed chamber, and a cell sorting monitoring system for monitoring and displaying the whole cell sorting process, which are sequentially connected with the sample bottle through a connecting tube, are arranged in the sealed chamber. The sorting apparatus has a good sorting effect, can effectively prevent the cross contamination among patients and the hybridization of tumor cells, can reach high-efficiency, high-quality and zero-pollution automatic cell sorting, is in favor of reducing the medical cost, is also convenient for the allogeneic cell sorting, is suitable for more diseases, and has wide uses.
