DEWAR FLASK Meaning and
Definition
-
A Dewar flask, also known as a vacuum flask or a thermos, is a specially designed vessel used for storing and transporting substances at extremely low temperatures. It is named after its inventor, Sir James Dewar, a Scottish chemist and physicist.
The Dewar flask consists of two separate walls with a vacuum between them, which serves as an insulating barrier to minimize heat transfer and maintain the temperature of the contents over an extended period. The inner wall of the flask is typically made of glass or a similar material that has a very low thermal conductivity, while the outer wall is made of metal or sturdy plastic for protection.
The construction of the Dewar flask makes it ideal for preserving extremely cold liquids, such as liquid nitrogen or helium, by preventing heat from entering or escaping the container. This makes it invaluable in various scientific and industrial applications, including cryogenics, biological sample preservation, and medical storage.
Furthermore, Dewar flasks often feature a stopper or lid with a seal to prevent air from entering or escaping the flask, ensuring the contents' stability and preventing contamination.
In conclusion, a Dewar flask is a specialized double-walled container with a vacuum insulation used for storing and transporting substances at extremely low temperatures. Its innovative design allows for efficient temperature preservation, making it a vital tool in various fields of research, industry, and medicine.

Etymology of DEWAR FLASK
The term "Dewar flask" is named after its inventor, James Dewar. Sir James Dewar was a Scottish physicist and chemist who developed the first practical vacuum flask in the late 19th century. The flask was primarily used for storing and transporting liquified gases, and it became widely known as the "Dewar flask" to honor its creator. Today, the term "Dewar flask" is commonly used to refer to any double-walled, insulated container used for storing and preserving temperature-sensitive substances.
