A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. The resulting low pressure, commonly referred to as a vacuum, allows researchers to conduct physical experiments or to test mechanical devices which must operate in outer space (for example).

The Roots blower is one of the most common type of vacuum pumps A vacuum pump is a pump that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. ... Look up Vacuum in Wiktionary, the free dictionary. ... Layers of Atmosphere - not to scale (NOAA) Outer space, also simply called space, refers to the relatively empty regions of the universe outside the atmospheres of celestial bodies. ...
Vacuum became a valuable industrial tool in the 20th century with the introduction of the light bulb and vacuum tube, and a wide array of vacuum technology has since become available.
Vacuum fluctuations may also be related to the so-called cosmological constant in the theory of gravitation, if indeed this entity were to be observed in nature on a macroscopic scale.
Vacuum is often also measured using micrometers of mercury, the barometric scale, or as a percentage of atmospheric pressure in bars or atmospheres.
The most common vacuum degas chamber is a cylindrical vessel, fitted with vacuum control valve, vacuum release valve, vacuum dial gauge, L type gasket and a clear acrylic or metal lid.
Vacuum traps to protect the vacuum pump from contaminates from the degassing process and to also prevent any backstreaming of pump oil into the vacuum lines or chamber.
The vacuumchambers are equipped with a relative 0-30 in HG vacuum gauge, which is mainly used to determine that rough vacuum level.
