Any container that uses liquid nitrogen to store samples will inevitably have the problem of liquid nitrogen supplementation. This is true for open-top liquid nitrogen tanks, and the same is true for gas-phase liquid nitrogen storage tanks! Liquid nitrogen is used in different ways, but the natural volatilization of liquid nitrogen is the same, and there are times when it is used up.
There are various and simple ways to replenish liquid nitrogen in the open liquid nitrogen tank, such as manual replenishment, gas company or liquid nitrogen pump;
In comparison, the gas-phase liquid nitrogen storage tank is single, its replenishment is fixed, the method is automatic, and the tool is “self-pressurized liquid nitrogen tank”!
As mentioned above, the method is automatic, and its rehydration is automatically set by the system, controlled by the temperature-sensing program!
Before putting into use, the user needs to pre-set the height of rehydration and stop the height of rehydration;
During normal use, the intelligent monitoring and management system monitors the liquid level in real time, and judges it according to the information transmitted by the temperature sensor and the liquid level sensor.
When the liquid level is low and the temperature is high, the liquid replenishment will be automatically turned on. When the liquid level is too low or too high, an alarm will be issued to notify the manager to check whether there is insufficient liquid nitrogen in the liquid replenishment container.
Now it is very clear that the gas-phase liquid nitrogen storage tank will automatically replenish liquid nitrogen, but attention should be paid to the liquid capacity in the liquid nitrogen replenishment tank!
