Sample transfer device

The utility model discloses a sample transfer device, and relates to the technical field of sample transfer. The cold air cabinet comprises a base, a cabinet body is fixedly connected to the upper surface of the base, an air pump is arranged in the cabinet body, an air outlet of the air pump is communicated with a cold air box, a refrigerator arranged in the cold air box is connected with an external electric appliance element to emit cold air, and therefore cold air is input into the cold air box; cold air in a cold air box is input into a hose through an air outlet of an air pump, so that the cold air can refrigerate the interiors of the heat preservation cabinets along an air conveying pipe and a pipeline, a plurality of groups of heat preservation cabinets can be transferred in a large-batch mode at a time through the arranged heat preservation cabinets, and the problems that at present, dyed cells need to be detected in a large-batch mode, and the detection efficiency is high are solved. Moreover, the dy
