We did this once upon a time when someone wanted to run below the dew point
of our house air. Not sure how long it will last however….

Hi Jun,
I would recommend using the boiloff from a liquid nitrogen dewar. It will
last longer and you can avoid using magnetically attractive cylinders.
Cheers,

Hi Jun,
I did it once before. Depending on the usage, those tanks can run out pretty
fast. I would suggest to put a T to connect two tanks. Just swap it when
one is running low.
Good luck.

Hello All,
There will be a house nitrogen shutdown for 3 day in my building. To keep the
NMRs available for research, I am considering using high-pressure liquid
nitrogen tanks to supply three spectrometers with SampleCase: (1)NMR with
a IProbe and BCU I, (2) NMR with a Prodigy probe and BCU I, (3) NMR with a
Helium-cooled probe (no SampleCase).
Is this approach feasible? How many liquid nitrogen tank should I order?
I would greatly appreciate it if anyone could share their experience or
advice.
Best,
Jun
