Abstract

The invention discloses a set of instrument for quickly rewarming and cryopreserving a biological sample. The instrument comprises a sample container for accommodating the frozen biological sample, combined different electromagnetic and optical heat sources, a temperature control monitoring sensor and a comprehensive control heating system. Aiming at different biological samples, corresponding sample containers are designed and different electromagnetic heating modes are correspondingly provided through multi-directional temperature monitoring of the cryopreserved biological samples, so that the cryopreserved biological samples can be extremely rapidly heated, the heating rate is accurately controlled, and the temperature difference of different parts is reduced; therefore, the survival rate of the frozen biological sample after being heated can be improved.

Description

technical field [0001] The invention relates to the technical field of low-temperature preservation of biological materials, in particular to an efficient heating and rewarming method using different energy sources in combination. Background technique [0002] Long-term preservation of biological material can leave current surplus resources available for future needs, or increase the limited time available for shipping biological material resources. Long-term preservation methods for biological materials often require the use of cryogenic technology. The optimization of cryopreservation techniques will overcome problems such as solution damage and ice crystal formation. [0003] At present, there is a lack of means of ultra-high-speed uniform heating in the field of low-temperature biological preservation. The traditional water bath heating places the frozen samples in warm water at 37°C to heat up, and the heat is transferred from the surface of the frozen samples to the i...
