Long-term ultralow-temperature storage cabinet for biological sample

Abstract

The invention relates to a long-term ultralow-temperature storage cabinet for a biological sample. The long-term ultralow-temperature storage cabinet comprises a cabinet body; the front side of the cabinet body is provided with at least one a storage chamber formed by inwards sinking the side wall of the cabinet body; the outer surface of the cabinet body is provided with an insulating layer; the cabinet body is also provided with a gasified liquid nitrogen input port and a gasified liquid nitrogen output port which communicate with an inner cavity of the cabinet body and are controlled by numerical control of an external center; the long-term ultralow-temperature storage cabinet for the biological sample also comprises a storage container for storing the biological sample; the storage container comprises a container body adapted with the storage chamber; and an opening of the container body is provided with a sealing cover for sealing the container body. When the long-term ultralow-temperature storage cabinet for the biological sample is used for storing and taking the biological sample, a refrigerant cannot be leaked outwards, so that the biological sample is safer and lower in cost when being stored at low temperature for a long term.

Description

technical field [0001] The invention relates to a storage cabinet, in particular to a long-term ultra-low temperature storage cabinet for biological samples. Background technique [0002] The long-term ultra-low temperature storage cabinet for biological samples is a device that uses ultra-low temperature methods to preserve biological samples. The existing conventional ultra-low temperature biological sample storage devices, whether using liquid nitrogen tanks or other open or semi-open equipment, during storage, In particular, nitrogen leakage will inevitably occur when accessing samples. In this way, in addition to causing unnecessary waste of nitrogen, it is more likely that the experimenter will suffer from frostbite due to the leakage of nitrogen, which will bring harm to the operation of the operator. Come with some difficulty. Therefore, it is necessary to develop a new type of biological sample storage device that uses vaporized liquid nitrogen to store biological ...

[0002]Long-term ultra-low temperature storage cabinet for biological samples is a device that uses ultra-low temperature methods to preserve biological samples. The existing conventional ultra-low temperature biological sample storage devices, whether using liquid nitrogen Tanks or other open or semi-open equipment, nitrogen leakage will inevitably occur during storage, especially when accessing samples. In this way, in addition to unnecessary waste of nitrogen, it is more likely to cause The leakage of nitrogen gas caused frostbite to the experimenters and brought certain difficulties to the operation of the operators.
