The invention discloses a 
liquid nitrogen container and a cryogenic 
vial pick-and-place device. The 
liquid nitrogen container comprises a container body, and further comprises a rotary disc, a 
cryopreservation frame, a central shaft and a driving 
assembly, wherein an opening is formed in the container body; the rotary disc is arranged in the container body; the 
cryopreservation frame is supported by the rotary disc and comprises a plurality of 
layers of placement faces; the included angle between each placement face layer and the rotary disc is 40-60 degrees; the central shaft is perpendicularly arranged with and fixedly connected with the rotary disc; the driving 
assembly is electrically connected with the central shaft and used for driving the central shaft to rotate; and the central shaft is used for driving the 
cryopreservation frame to rotate through the rotary disc to reach the opening of the container body. By adoption of the 
liquid nitrogen container and the cryogenic 
vial pick-and-place device, the 
workload of operating personnel is reduced, the error rate of manual picking of cryogenic vials is lowered, and the potential safety 
hazard for the operating personnel is avoided. The 
liquid nitrogen container and the cryogenic 
vial pick-and-place device are particularly suitable for the work of picking cryogenic vials in a high-capacity biological sample 
bank, and meet the technical requirement for storage in the high-capacity biological sample 
bank.
