Deijan,
That has happened to me in the past on numerous occasions. What I learned to do was #1 not to open the valve all the way and #2 while the fill was taking place, to periodically (every 1-2 min) to turn it back and forth a little to be sure it isn't freezing.

Subject: AMMRL: Liquid valve is hard to turn off on the liquid nitrogen tank
Hello,
It maybe a trivial issue, but I didn't find any post on this issue before. The liquid valve on the LN2 tank we received this week became very hard to turn off after the LN2 refilling. I had to use a wrench to turn it off. Maybe the liquid valve is problematic. Is there anyway to know it before the refilling since it's not obvious when turning the liquid valve on. Thanks!
Not related to this, I read about the 'Bruker folders' discussion. Many of you know that the folder structure of the Bruker NMR data has been like it is for 20+ years, from previous XWinNMR to current TopSpin. It's actually kind of neat.
