Does a vapor phase liquid nitrogen storage system require electricity?

In routine experimental research, liquid nitrogen tanks are basically used for cryogenic preservation of samples such as embryos and tissues;

It is an aluminum liquid nitrogen container that stores samples by immersing them in liquid nitrogen.

However, large-scale experimental research is different from the establishment of a sample database. It is larger in volume, difficult to manage, and has more sample data to record.Therefore, these places will switch to vapor-phase liquid nitrogen storage systems for long-term storage of large amounts of biological samples.

The vapor-phase liquid nitrogen storage system is a stainless steel liquid nitrogen cryogenic tank, which can also be called a vapor-phase liquid nitrogen freezer. It has a large volume of 350-1800 liters and has two internal storage spaces for samples and liquid nitrogen. It uses the same storage space as conventional liquid nitrogen. The tank is stored in a completely different vapor phase mode, so the amount of liquid nitrogen required is not close to the total volume of the container.

Seeing this, some users may want to ask, it preserves samples in the vapor phase instead of immersing them in liquid nitrogen. Where does its vapor phase come from? Does it need to be powered on like the -80°C cryogenic refrigerator?

Yeah?

Answer: The container itself is not required, but the intelligent monitoring and management system does!

As mentioned earlier, the vapor-phase liquid nitrogen storage system is divided into two storage spaces: liquid nitrogen and sample. An evaporator is installed in the storage location of the liquid nitrogen. The evaporator will automatically detect when the system detects that the temperature in the container is higher than the set value. When turned on, the liquid nitrogen vaporizes and rises to the sample storage area in the form of nitrogen to maintain the cryogenic of the entire container.

Therefore, the vapor-phase liquid nitrogen container itself does not require electricity.

However, peripherals such as intelligent monitoring and management systems are needed. It is similar to a microcomputer. At the mouth of the vapor-phase liquid nitrogen storage tank, part of the wiring is connected to the temperature sensing part inside the container, and the other part is connected to the external power supply. It requires power supply to ensure screen display and remote alarm, etc., just like our computers!

To sum up, whether the vapor-phase liquid nitrogen storage system uses electricity depends on which part it is!
