Speak to Bruker - they have an interesting collection of pictures how *not* to do it (spoiler: bang).

I guess if you can get the bulk plant or LN2 generator close enough.. be nice if you can pull it off.

Dear colleagues,
As part of the design of a new Chemistry building, we are looking into getting
some liquid N2 "on tap", directly into the NMR room.
I am only aware of one NMR lab so far having implemented this (aside from biology
colleagues with small rooms, purpose-built for decanting) so I thought I'd pick
the brains in our community.
1/ Do you have such system installed and what do you use it for (decanting into open
top dewars, filling magnets, etc )?
a/ What are your safety features?
b/ Do you have specific training requirements for all coming into of the NMR facility?
c/ if you are filling magnets with the system, are the flow rate/pressure reliable?
d/ have you had any leaks?
2/ If you have considered such a system and have decided NOT to implement it, why did you decide against it?
a/ price?
b/reliability?
c/resistance from Safety Services?
d/other
Any experience/comments you shared on this will be greatly appreciated. Thank you!
I'll summarize the responses for the benefit of the group/archive.
Kind regards,
Cecile
