Liquid nitrogen tanks, according to the classification of liquid nitrogen status, can be divided into liquid-phase liquid nitrogen tanks and gas-phase liquid nitrogen tanks; Biological samples in liquid-phase liquid nitrogen tanks are stored under the surface of liquid nitrogen, and the samples are immersed in liquid nitrogen. Biological samples in gas-phase liquid nitrogen tanks are stored in a nitrogen atmosphere in the liquid nitrogen temperature zone without direct immersion. The gas-phase liquid nitrogen tank is made of stainless steel, which has the advantages of corrosion resistance, low temperature resistance, high strength, and high load-bearing. It uses high vacuum insulation technology to reduce the evaporation rate of liquid nitrogen and maintain stable pressure in the tank. The characteristics of gas phase liquid nitrogen tanks are: 1. Designed for gas-phase storage of samples. Gas-phase storage does not require direct soaking in liquid nitrogen, which can avoid the risk of cross-infection between samples. 2. The neck temperature can reach -190�°C. This diameter design, coupled with vacuum technology, reduces the evaporation loss rate of liquid nitrogen and lowers operating costs. 3. Convenient access, 2-level steps and partitioned tray rotation design, superheated gas is automatically eliminated during fluid replenishment. 4. Equipped with an intelligent monitoring system to monitor liquid level, temperature, and remaining liquid nitrogen capacity in real time. It can be connected to the monitoring terminal to achieve centralized data management. It can actively alarm in 19 states and can send alarm information to mobile phones to ensure the safety of liquid nitrogen tanks and samples in an all-round way. 5. Has one-click defog function. 6. The structure has an earthquake-resistant design to prevent damage to the tank caused by earthquakes. The large capacity of the gas-phase liquid nitrogen tank determines its advantage in long-term storage of large batches of biological samples. The combination of modern technology and stainless steel storage tanks makes it easy and convenient to store large batches of samples.
