Is liquid nitrogen flammable?
Nitrogen is non-toxic, odorless, and colorless. It is relatively inert and is not flammable. … LN2 displays the Leidenfrost effect, which means it boils so rapidly that it surrounds surfaces with an insulating layer of nitrogen gas.
Is liquid nitrogen expensive?
When delivered in Dewar flasks, liquid nitrogen costs about $2 per gallon but when delivered in bulk storage tanks, it costs about $0.50 per gallon. Nonetheless, the atmosphere is about 78 percent nitrogen so liquid nitrogen can be manufactured anywhere and will still be relatively cheap.

6 monthsAssuming that this is a well-maintained high-vacuum Dewar of typical commercial construction, I would expect a hold time of at least 6 months. The Dewar manufacturer should list specifications for either static hold time or normal evaporation rate.
Can liquid nitrogen be stored at room temperature?
Liquid nitrogen should only be stored in well-ventilated areas. A vapor cloud or plume, created by water vapor condensation, can be evidence of a release. As the gas warms up to room temperature, the vapor cloud may not be visible, but the danger may still be present.
