Yes this is a problem! One thing that can be done about it is to bake the dewar while pulling a vacuum on it or another is the use of ultraviolet light.(To dry it up) I don't know what else I can tell
you without revealing anything that is proprietary.

<<File: ENVELOPE.TXT>>
Greetings:
I have a question regarding moisture in LN2 Dewars. My assumption is under
normal conditions, the moisture would be frozen solid and have a very low
vapor pressure, but what happens to the ice as the dewar becomes empty...
anyone else experienced a problem that could be attributed to moisture in a
LN2 system?
Thanks,
Tom Ostertag
