You seek to optimise the management of your biological products stored in liquid nitrogen, and rationalize the cryogenic flows :

For the long-term preservation of biological products, liquid nitrogen (- 196 °C) makes it possible to produce optimal storage conditions: in fact, at this temperature, cellular division and enzyme systems are drastically slowed down or even halted altogeter. However, in order to limit the cellular lesions induced by extremely low temperatures, it is wise to use cryo-protectors, which slow down the formation of ice-crystals in the cells.
