Liquid nitrogen dewars
A series of liquid nitrogen Dewars based on a proven design and construction provide a range of capacities to suit individual laboratory storage and liquid nitrogen handling requirements. These Dewars combine the qualities of strength, high thermal efficiency and ease of handling. A range of small dewars are very useful for handling the small quantities of liquid nitrogen needed for freezing samples or for topping up anti-contamination Dewars. They all have quality borosilicate glass inserts protected by polypropylene or metal cases. All glass inserts are replaceable.
