A self-pressurising dewar (silver) being filled with liquid nitrogen from a larger storage tank (white). A cryogenic storage dewar (or simply dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible.
Volumetric flask is used for preparing liquids with volumes of high precision. It is a flask with an approximately pear-shaped body and a long neck with a circumferential fill line. Dewar flask is a double-walled flask having a near-vacuum between the two walls. These come in a variety of shapes and sizes; some are large and tube-like, others ...
Terraria: Otherworld was a separate game in the series which was announced in February 2015 and planned for release later that year. [66] Otherworld tasked the player with trying to purify the world of the Corruption, which was to be achieved mainly by finding and activating "purifying towers" that push back the spread of the Corruption.
Dewar may refer to: Clan Dewar; Dewar (caste), a fishing caste from India; Vacuum flask (also known as a Dewar flask), a vacuum-insulated container used to maintain internal temperature for extended periods, named for British chemist James Dewar. Cryogenic storage dewar, a specialized vacuum flask for extremely cold fluids
To function effectively, the FPA must be cooled and calibrated. In other applications, a CLU's IR detectors are cooled using a Dewar flask and a closed-cycle Stirling engine, but there is insufficient space in the missile for a similar solution.

Actually, it should be merged under vacuum flask per WP:NC(CN). --Mathew5000 05:20, 22 June 2006 (UTC) A "dewer" or a "dewer flask" is a very specific object used for cryogenics, and is not known as a "vacuum flask", which is a household item and is always a different thing.
