Liquid Nitrogen Plant : The LN2 most commonly used for cryopreservation of cells and microbes. Also used in Liquid Helium plant for precooling, in NMR for prevent heat leak into LHe, High temperature superconductors etc. Liquid Helium Plant : The liquid helium produced can be used for cooling purposes down to 2 K for doing various experiments at low temperatures. Liquid helium can also be used for cooling superconducting magnets such as the ones used in NMR machines, MRI machines, etc.
