Those tanks are not designed to provide the sort of thermal insulation
you need to keep liquid nitrogen for any length of time. An ordinary
thermos bottle is a better bet. Also, you have to be very careful not
to use some tank that seals shut, because as the nitrogen boils the
pressure builds up, and your tank could explode.
