Description

technical field [0001] The invention belongs to the technical field of low-temperature tissue embedding of biological samples, and in particular relates to a temperature control system for low-temperature tissue embedding. Background technique [0002] The patented technology with Chinese patent number 201610159556.4 proposes a set of embedded embedding solutions for low-temperature biological sample storage, which saves a lot of time, improves work efficiency, saves a lot of storage space, and realizes Automated batch scan storage. [0003] Although the above-mentioned technology solves the problem of batch storage of samples, in the subsequent use process, it is necessary to implement thawing and refreezing operations on the embedded tags. In the previous operation process, researchers generally used body temperature melting and refrigerator cold environment freezing. It is time-consuming and laborious, and it is not conducive to batch operations. If the thawing or refree...

[0003] Although the above-mentioned technology solves the problem of batch storage of samples, in the subsequent use process, it is necessary to implement thawing and refreezing operations on the embedded tags. In the previous operation process, researchers generally used body temperature melting and refrigerator cold environment freezing. Time-consuming and laborious, and not conducive to batch operations, if the thawing or refreezing process lasts, it may also affect the nucleic acid or protein information of the embedded biological samples
