In life science research, liquid nitrogen is a commonly used freezing medium, and the container that stores it has become an important experimental tool. During the experiment, in order to stabilize the low-temperature storage environment of the sample, regular replenishment is required to ensure adequate supply. Because liquid nitrogen is volatile, the amount of liquid nitrogen decreases over time. Therefore, self-pressurizing liquid nitrogen tanks designed for liquid nitrogen supply are widely used and are very popular in scientific research institutions, laboratories, health industries and other places.
What is a self-pressurizing liquid nitrogen tank?
Answer: It is a liquid nitrogen supply equipment. It can also be called a pressurized liquid nitrogen tank!
Its principle of supplying liquid nitrogen is very simple, which is to use the evaporation of liquid nitrogen to generate pressure to realize the discharge of liquid nitrogen.
There is a valve on the top of its tank that controls the pressure increase. Only when a certain pressure is reached can the liquid discharge be realized. So, when the pressure reaches what level, can this function be realized?
When the pressure reaches 0.02MPa-
