Liquid nitrogen container and cryogenic vial pick-and-place device

Abstract

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.

Description

technical field [0001] The invention relates to a liquid nitrogen tank and a freezing tube access device. Background technique [0002] The deep cryogenic biological sample bank is an important basic equipment for research in the fields of medicine and biology. The low temperature storage of liquid nitrogen can keep biological tissues such as blood, stem cells and immune cells alive for a long time. [0003] At present, the liquid nitrogen storage tank is a manual structure. When selecting the cryopreservation tube, the operator needs to open the tank cover, reach into the tank and take out the entire cryopreservation plate before picking out a single cryopreservation tube. In addition, it is also necessary to take out the entire cryopreservation plate and store it in a single cryopreservation tube. This way of access exposes the entire cryopreservation plate to an environment above -196°C, which affects the biological properties of cells stored in other cryopreservation tub...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that when the cryopreservation tubes are manually picked out from the liquid nitrogen tank, the biological properties of the cells stored in the remaining cryopreservation tubes are affected, and the operation efficiency is low and the error rate is high.
