[0002] Reproductive medicine preservation is often used to store sperm, egg and embryo samples in liquid nitrogen to ensure activity. In the prior art, sperm, egg and embryo samples are generally placed in test tubes, and then the test tubes are stored in liquid nitrogen. In nitrogen, when the specimen is preserved, if the specimen is placed in the lower part of the liquid nitrogen tank, it is very inconvenient to place and take the specimen. If the specimen is preserved in the upper part of the liquid nitrogen tank, although the Henaqu The specimens are relatively convenient, but after a period of storage, due to the volatilization of liquid nitrogen, the specimens may not be completely immersed in liquid nitrogen, resulting in damage to the specimens, and the preservation of the specimens is inconvenient
