2. Vacuum flask - Wikipedia

   en.wikipedia.org/wiki/Vacuum_flask

   Vacuum flasks are often used as insulated shipping containers. Extremely large or long vacuum flasks sometimes cannot fully support the inner flask from the neck alone, so additional support is provided by spacers between the interior and exterior shell. These spacers act as a thermal bridge and partially reduce the insulating properties of the ...

3. Cryogenic storage dewar - Wikipedia

   en.wikipedia.org/wiki/Cryogenic_storage_dewar

   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.

4. Vacuum distillation - Wikipedia

   en.wikipedia.org/wiki/Vacuum_distillation

   Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.

5. Büchner flask - Wikipedia

   en.wikipedia.org/wiki/Büchner_flask

   Cross section of a Büchner Flask. Note the hose barb pointing right for attaching a vacuum source. A Büchner flask, also known as a vacuum flask, [1] filter flask, suction flask, side-arm flask, or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.

6. Suction filtration - Wikipedia

   en.wikipedia.org/wiki/Suction_filtration

   Diagram of the vacuum filtration apparatus. By flowing through the aspirator, water will suck out the air contained in the vacuum flask and the Büchner flask.There is therefore a difference in pressure between the exterior and the interior of the flasks : the contents of the Büchner funnel are sucked towards the vacuum flask.

   We can’t fight global warming by carpooling to work or recycling plastics alone. It will require help on a bigger scale. Here is a simple how-to kit for transitioning to a low-carbon economy.
