There is a small gas-liquid nitrogen tank,you can also call it a small gas-liquid tank!It is also specially used for gas phase storage of stem cells,embryos,semen and other biological samples.It has moderate capacity,low liquid nitrogen loss,easy operation,and is more suitable for laboratory gas phase storage of small quantities of samples.
Its gas-phase preservation principle is very simple.It is based on the characteristics of liquid nitrogen having a boiling point of -196.56°C under normal pressure and the natural formation of nitrogen.The area of the small gas-liquid phase liquid nitrogen tank is divided into two,liquid nitrogen is placed at the bottom,and the sample is frozen.The rack is suspended above the liquid nitrogen,and with the help of the natural volatilization of the liquid nitrogen,a low-temperature environment is formed in the container.
That's right,the small gas-liquid phase tank is a smaller version of the YDD series gas-phase liquid nitrogen tank.
