WebDewar flasks are designed as insulating vessels and are primarily used for cryogenic applications. A Dewar flask actually consists of two flasks placed one within the other, joined at the top or neck of the flasks. The space or gap between the two flasks consists of a near-vacuum and functions to prevent heat transfer, insulating the inner flask.
