Subject: 3 Re: [DCHAS-L] LN2 and NMR
I'm somewhat curious as to
why anyone would
not be using "flexible" (until it cools to LN2 temp) metal-clad
cryogenic hoses
for this service. I would never recommend using "plain rubber
tubing" to transfer LN2. The cost of the
appropriate
personal protective equipment should not be an excuse for not using
it.
