Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a low-temperature storage module. Background Art

[0002] When testing biological samples, such as test samples or probes, the test samples or probes need to be kept at a set low temperature during storage in order to be ready for use. At present, the test samples or probes are generally placed directly in a refrigerated structure (such as a refrigeration device). When used, samples need to be taken out repeatedly manually, which requires a large amount of manual work. At the same time, the test samples or probes cannot be kept in a constant low-temperature environment during the process of taking and placing, and consumables (such as test tube racks containing test tubes, ELISA plates, PCR plates, deep-well plates, etc.) and adapters for placing consumables will produce a certain amount of condensed water in a low-temperature environment. When taking out samples from a low-temperature environment, the change in temperature will cause an increase in condensed water outside the consumables. If it enters the test samples or probes, it will affect the test results. Utility Model Content
