Vacuum is created through use of a vacuum pump or aspirator pump, to facilitate specific biological preparations, such as inclusions or disinfection of material for in vitro culture, etc.
A void, space without matter.
In this document this term refers to any pressure that is less than atmospheric.
A vacuum is a space that has no pressure and no molecules inside. It is truly and empty space. Although space has a very low pressure (almost a vacuum), there are still particles out there. MORE INFORMATION: Matter
Negative pressure commonly expressed in inches of mercury ("Hg), millimeters of mercury (mmHg) which is equal to torr. One atmosphere equals 14.7 psia (0 psig), 29.92"Hg (0"Hg absolute), 760mm Hg, 760 torr or 1,013 mbar.
Can be used to remove water during a water change (syphon), and can clean the gravel and remove wastes.
A device that uses suction to collect dirt from the bottom and sides of a pool. Most common is a vacuum head with wheels that attaches to a pole and is connected to the suction line. Some automatic pool cleaners fall into this category.

removal or evacuation of air and gas from a given space.
SA space which contains little or no matter.
Vacuum is a pressure lower than atmospheric. Except in outer space, vacuums occur only in closed systems.
the absence of matter void: an empty area or space; 'the huge desert voids'; 'the emptiness of outer space'; 'without their support he'll be ruling in a vacuum' a region that is devoid of matter an electrical home appliance that cleans by suction
A vacuum (sometimes vacuüm) is a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure. The word comes from the Latin term for 'empty,' but in reality, no volume of space can ever be perfectly empty. ...
Vacuum is the name of a swedish song-writing/production duo consisting of Mattias Lindblom and Anders Wollbeck. They also work together as a pop-group under the same name. As songwriters they have written hits for artists such as Monrose, Tarja Turunen and Rachel Stevens to name a few. ...
