Description

Technical Field

[0001] The utility model relates to the technical field of biological sample storage, in particular to a dual-mode refrigeration ultra-low temperature storage and access device. Background Art

[0002] Currently used low-temperature storage devices generally use compressors for refrigeration. However, in the event of a sudden power outage, the power outage cannot refrigerate the sample, causing the sample cell structure in the storage device to be destroyed. Secondly, existing refrigerators with hinged doors usually require the entire door to be opened, exposing the low-temperature area behind the door before taking and placing low-temperature stored objects. Frequent temperature changes have an adverse effect on the objects stored in the low-temperature area, especially in the field of biological sample storage. Biological samples are particularly sensitive to temperature changes and can easily become inactivated. At the same time, the humid gas in the operating cabin of existing storage devices can easily corrode the internal mechanisms. To this end, the inventors designed a dual-mode refrigeration ultra-low temperature storage and access device. Utility Model Content
