ESEM is down for the weekend with a vacuum problem. I’ll fix it Monday
We have 3 stainless steel dewar tanks for dispensing liquid nitrogen in room 637 (Sample Prep). One of them has had a leak and was unusable for several months. I repaired it yesterday. If you find that the dewar in the outer room is empty get the 2nd one in the back room. There is no need to take the hose off of the 2nd dewar any more.
