- | Liquid nitrogen can be stored in the Dewar for a surprisingly long time, but it does gradually boil off. (The insulation is very good but obviously not perfect. A small amount is continually vaporized so the liquid remains below the boiling point.) | + | If you want some liquid nitrogen for a demonstration please contact the demo room in advance. Unless it's specifically requested we don't keep liquid nitrogen in the demo room. When it's needed, it's picked up from the chemistry building. |
