Abstract

The invention belongs to the technical field of cryopreservation, and discloses a liquid nitrogen container, which comprises a first tank and a second tank. The first tank comprises a first tank opening, a glass window, and a push rod. The second tank comprises a rotating disc, a bottom disc, and a central shaft. Along the circumferential direction of the rotating disc, multiple storage frames forstoring cryopreservation supports are arranged; a corrugated pipe is fixedly connected under the storage frames; the corrugated pipe is connected to an air pump arranged in the first tank; the air pump fills helium into the corrugated pipe; the corrugated pipe is expanded to drive the cryopreservation supports to enter the first tank, the push rod is driven to push the samples, an operator does not need to take the samples by hands, thus the operator will not be hurt by the liquid nitrogen, and moreover, liquid nitrogen leakage is prevented.

Description

technical field [0001] The invention belongs to the technical field of ultra-low temperature preservation equipment, and specifically discloses a liquid nitrogen tank. Background technique [0002] With the continuous development of science and technology, the use of liquid nitrogen is becoming more and more extensive, and the utilization rate of liquid nitrogen tanks is also increasing. Liquid nitrogen tanks are mainly used for storage and transportation of liquid nitrogen containers. In addition, they are also used in many applications such as medical surgery refrigeration, active preservation of biological samples, and cryogenic treatment of metal materials. Liquid nitrogen has a long storage time and is suitable for long-term storage of active biological materials in a static room; when needed, it can be used after thawing and rewarming. [0003] At present, the existing liquid nitrogen tanks have the following problems in actual use: when selecting frozen samples, the ...
