Abstract
A sample cooling and storage method is provided. A method of programmed cooling is divided into a method of cooling in several stages corresponding to a standard ambient cooling curve. In each stage of cooling, whether samples need to be raised or lowered is determined by checking whether an actual ambient temperature Tis equal to a target ambient temperature w, so that the actual ambient temperature Tis consistent with the target ambient temperature w, until the actual ambient temperature Tis consistent with a target temperature Tfor this stage of cooling. After each stage of cooling in sequence, samples finally reach a temperature required for cryogenic storage, and are directly stored in a liquid nitrogen storage box. The sample cooling and storage method is capable of simultaneously realizing programmed cooling and sample storage, which is convenient for treating single-layer samples.
