A while back, someone asked me how long my LN2 Dewar could keep LN2 in
it? I estimated at that time 6 months.

It holds 34 Liters and is a super insulated, non-pressurized vessel which
cost around a $1000. Over the course of 2 months after being filled to it's
max., I estimate the loss of 6 liters. Not sure if that loss would increase
as the vessel empties, but for sure, with moderate usage, it lasts us six
