Abstract

The present application discloses a sample cryogenic storage pipe. The sample cryogenic storage pipe includes a pipe body and a one-piece pipe cap removably configured in the pipe body; there is an opening portion on an upper portion of the pipe body, a sleeve of the pipe body is provided below the opening portion, and a sealed cavity is formed between the sleeve and a pipe wall of the pipe body; the pipe cap includes a pipe cap mating portion and a sample loading rod integrally formed with the pipe cap mating portion, and the sample loading rod, on at least one side thereof, is provided with a storage groove for storing a sample; and the pipe cap mating portion is removably configured on the opening portion of the pipe body, and the sample loading rod is able to be inserted into the sleeve of the pipe body or be removed from the sleeve of the pipe body. The present application also discloses a sample cryogenic storage device. The sample cryogenic storage pipe and device provided by the present application have features of simple structure and easy operation where there is no residual liquid nitrogen when in use.

Claims
