This invention provides a low-temperature storage device for blood protein detection, relating to the field of blood protein detection. It includes a storage unit comprising a cabinet, six storage cavities located on the front of the cabinet, a placement platform movably connected to the inner cavity of each storage cavity, and a test tube slot located on the top of the placement platform for positioning and placing sample tubes. This invention designs six independent storage cavities, each with its own placement platform, capable of holding different types of blood protein samples. Personnel can differentiate and control the temperature according to the sample's needs, facilitating later retrieval and preventing the uniform internal temperature problem caused by a monolithic design, thus improving storage efficiency. Furthermore, a microcontroller can independently control the operating state of the corresponding semiconductor cooling chip based on temperature information from the temperature sensor in each storage cavity, achieving precise temperature control and meeting the diverse storage temperature requirements of different blood protein samples.
