Embodiment

[0031] see Figure 1 to Figure 4 A long-term ultra-low temperature storage cabinet for biological samples in a preferred embodiment of the present invention includes a cabinet body 1, and a plurality of storage rooms 2 formed by inward depressions of the side walls of the cabinet body are arranged on the front side of the cabinet body, and the size thereof can be Accommodates single biological sample containers to combined biological sample containers to meet different storage needs. The outer surface of the cabinet is provided with an insulation layer, and the two ends of the cabinet are also provided with a gasified liquid nitrogen input port 3 and a gasified liquid nitrogen output port 4 that are connected to the inner cavity of the cabinet. In practical applications, the gasified liquid nitrogen input port and gas There is a considerable distance between the output ports of the gasified liquid nitrogen. For example, the input port of the gasified liquid nitrogen can be loc...

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 ...
