Profound hypothermia automatic storing and taking mechanism for biological samples

Abstract

The invention relates to the technical field of deep hypothermia refrigerators, in particular to a biological sample deep hypothermia automatic storing and taking mechanism which comprises a tank body and a cryopreservation frame installed in the tank body. Wherein the upper part of the tank body is fixedly connected with a top plate, the end face of the top plate is provided with a grabbing unit and a driving unit, the end face of the top plate is provided with a channel, and the grabbing unit enters the tank body along the channel to grab and put samples in the cryopreservation frame; the grabbing unit grabs the cryopreservation tubes with biological samples from the temporary storage space, the cryopreservation tubes enter the liquid nitrogen tank through cooperation of the transverse transferring mechanism and the longitudinal transferring mechanism, the driving unit is used for controlling the storage units to rotate, and accurate positioning and storage of the cryopreservation tubes in different storage layers are achieved. The biological sample storage efficiency and accuracy are improved, meanwhile, the storage capacity is enlarged, and the method is suitable for long-term storage of large-scale biological samples.
