*Brief Features:
-The face-to-face surfaces of the two walls of a Dewar flask are silver plated or polished to reduce heat radiation;
-The upper part or the neck of the inner wall is made of non-conductive materials to reduce heat transfer through solid materials;
-The Dewar bottle is widely used in liquefied gas production, storage, and transport;
-It is also a vacuum-insulated container commonly found in scientific research, medical health care and oil drilling.
