We have that set-up. A 180L, 230psi dewar lasts us about 30 days for our 400 MHz Avance II+ from Bruker.

Subject: AMMRL: Liquid Nitrogen use
Hi Everyone,
I am wondering if any of you has an idea of how much liquid nitrogen would be used per spectrometer assuming that you run with nitrogen gas as the gas source taken from a liquid N2 tank outside the building. I am asking because we are considering tapping into a large tank for some of our NMR systems and they need to know how much liquid we could expect to use/system. We would plan to use it for sample eject, spinning, VT, and inflation of anit-vibration legs. If any of you have such a set-up, I would appreciate any cost info you can give.
Best,
Greg
