A safe means of transporting, storing, handling and dispensing liquid nitrogen. Wide mouth opening allows for easy filling and dispensing. Manufactured from borosilicate glass, these flasks are very heavily insulated, and wrapped with an exterior aluminum metal housing that extends nearly to the top rim of the flask adding extra safety protection. All flasks have a special vented, polypropylene stopper to minimize evaporation. Smaller trap may be used with a vacuum trap apparatus for cooling purposes.
