Abstract
A biological sample vitrification carrier and a method for freezing a biological sample are provided. Specifically, the carrier comprises a main body and a sealing cap that form a sealed frozen sample placing region. Frozen liquid circulating in a liquid circulating channel in the main body contacts with an outer surface of the frozen sample placing region and cools a biological sample in the frozen sample placing region. The biological sample vitrification carrier and the method in the present invention have the advantages of safety, nontoxicity and high vitrification and rewarming operation efficiency and have wide application prospects in the field of biological sample freezing.
