Abstract

The present invention relates to an automated deep-low temperature cold chain storage biological sample device and a method for using the same. The device includes a shell and a storage device. A window and a controller are provided at the upper end of the shell. A first chamber and a second chamber are provided in the shell. A lifting channel is provided at the bottom of the window. Two docking ports are provided on the sides of the lifting channel. The docking ports are connected to a conveying channel. A liquid nitrogen filling system, a refrigeration system, and a conveying assembly are installed in the shell. The refrigeration system includes a condenser group and a first compressor, a second compressor, a first evaporator, a second evaporator, and a diverter that are independently fluidically connected to the condenser group. The conveying assembly includes a lifting mechanism, a first conveyor, and a second conveyor. The present invention has a high degree of automation and can store biological samples in a low-temperature mode or a deep-low temperature mode. It is convenient to store and has good low-temperature and frozen storage effects.
