  2. Vacuum flask - Wikipedia

    en.wikipedia.org/wiki/Vacuum_flask

    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.

  3. Cryogenic storage dewar - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_storage_dewar

    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. It is named after inventor James Dewar, who developed it for his own work.

  4. Cold trap - Wikipedia

    en.wikipedia.org/wiki/Cold_trap

    Cold trap immersed in cold medium in Dewar flask. Some workers prefer the opposite arrangement, where vapors flow down the wall of the trap, and are sucked up the inner tube; this reduces blockage.

[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.

  7. Sorption pump - Wikipedia

    en.wikipedia.org/wiki/Sorption_pump

    The sorption pump is a cyclic pump and its cycle has 3 phases: sorption, desorption and regeneration. In the sorption phase the pump is actually used to create a vacuum. . This is achieved by cooling the pump body to low temperatures, typically by immersing it in a Dewar flask filled with liquid nitro

  8. Dewar - Wikipedia

    en.wikipedia.org/wiki/Dewar

    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

  9. Laboratory flask - Wikipedia

    en.wikipedia.org/wiki/Laboratory_flask

    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 ...
