Vatican liquid nitrogen freezer KGSQ cryogenic storage vessel

China [CN]

In the laboratory, cell samples need to be placed in liquid nitrogen for cryogenic storage. However, some samples must not only be cryopreserved, but also stored in the gas phase without contact with liquid nitrogen. The former can be solved with a conventional liquid nitrogen tank, and the latter can also be solved with a gas-phase liquid nitrogen tank. However, the capacity of gas phase tanks is relatively large, above 350 liters, and the samples that laboratories need to store in gas phase are not always large. When the quantity is small, using gas phase tanks to store them is really overkill. So how to preserve these samples?

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. At this point, is there a familiar and unfamiliar feeling?

That's right, the small gas-liquid phase tank is a smaller version of the YDD series gas-phase liquid nitrogen tank. Except for the difference in material and capacity, the rest of the characteristics are the same. For example: compatible with gas-liquid phase dual-mode storage, intelligent management system, etc.; therefore, the principles between the two are also interoperable!

In short, the small gas-liquid phase tank makes up for the YDD series's demand for small-volume cell storage in terms of capacity. It is a lightweight and energy-saving gas-phase storage liquid nitrogen container specially designed for gas-phase storage of small-capacity cell samples.
