Technical Field
[0001] The utility model relates to the technical field of storage cabinets, in particular to a sample storage cabinet. Background Art
[0002] Sample storage cabinets are specialized devices designed for the safe and efficient storage of various laboratory samples, biological materials, chemical reagents, and pharmaceuticals. They are widely used in fields such as medicine, biological sciences, chemistry, pharmacy, and environmental science. Sample storage cabinets can be categorized into various types, including ambient temperature cabinets, refrigerated cabinets, frozen cabinets, and ultra-low temperature cabinets, depending on storage requirements.
[0003] Normal-temperature storage cabinets operate at higher temperatures, allowing biological samples to be more active and easier to access and test later. However, high temperatures also increase the rate of microbial growth, which can exacerbate the risk of biological samples spoiling during storage. For these reasons, the storage time of samples in open-air normal-temperature storage cabinets is often very limited.
[0004] From the above background technology, it can be known that the existing open room temperature storage cabinet has the defect of short sample storage time. Utility Model Content
[0005] In view of this, the present invention aims to provide a sample storage cabinet, which solves the defect of the open room temperature storage cabinet in the background art that the sample storage time is short.
