Abstract

A high-efficiency air-cooled gas-phase liquid nitrogen biological storage device and its use method and application relate to a biological storage device and its use method and application. The purpose of the invention is to solve the problems of large temperature difference between the upper and lower inside the tank body of the existing gas-phase liquid nitrogen biological storage tank and the large temperature fluctuation inside the tank body. The device consists of a tank, a control display, a centrifugal fan, a liquid nitrogen coil, a sample turntable, a central shaft, a grid and a cryogenic pump; the center of the lower surface of the upper cover of the tank is provided with a disc tuyere, a disc tuyere and a centrifugal fan. An air duct is arranged between the fans, and the liquid nitrogen coil is fixed between the centrifugal fan and the disc air outlet. The device is capable of rapid cooling operation and storage operation. The device is used in the storage of large mammalian organisms, cryopreservation racks, biological cells or viruses. The device and method of the invention solve the problems of large temperature difference between the upper and lower sides of the tank and large temperature fluctuations, and reduce the consumption of liquid nitrogen. The invention is suitable for gas-phase liquid nitrogen biological storage device and application.

Description

Technical field [0001] The present invention relates to a biological storage device and a method of use and application thereof. Background technique [0002] The liquid nitrogen cans are widely used in hospitals and laboratories, mainly divided into liquid phase storage and gas phase storage. Liquid nitrogen tanks are used for freezing of biological materials such as cells. At present, in the field of biological research and clinical treatment, gas-phase liquid nitrogen storage tanks can ensure long-term stable storage of cells, and can avoid multi-sample biocolid caused by liquid phases, especially in cord blood libraries, various stem cell libraries, biological tissue samples. Widely used in the library. [0003] The gas phase liquid nitrogen biological storage tank is constantly evaporated by liquid nitrogen in the tank so that the biological sample is in a low temperature liquid nitrogen vapor environment, thereby achieving the ultra-low temperature preservation of the sampl...
