Introduction to Dewar Flasks

Dewar flasks, commonly known as Dewar bottles or vacuum flasks,

Key Points in Overall Post-Weld Heat Treatment Quality Control

Content

Dewar flasks, commonly known as Dewar bottles or vacuum flasks, are specialized containers designed for the storage and transportation of cryogenic liquids, such as liquid nitrogen and oxygen. Named after their inventor Sir James Dewar, these bottles feature a double-walled design with a vacuum between the walls, minimizing heat transfer and maintaining extremely low temperatures.
