All the air is sucked from the top of a long glass tube that is dipping into a dish of mercury. Mercury barometer: barometer: In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured.The classic mercury barometer is designed as a glass tube about 3 feet high with one end open and the other end sealed. The tube is filled with mercury.
This glass tube sits upside down in a container, called the reservoir, which also contains mercury. The mercury level in the glass tube falls, creating a .
A classic mercury barometer is constructed from a 3-foot glass tube that is open at one end and sealed at the opposite end. The glass tube is filled with liquid mercury and rests upside-down in a reservoir of mercury. As the mercury moves down the glass tube, a vacuum is created.

Nobody told us about the dangers of mercury when I first started work. We used to handle it regularly when refilling u-tube manometers.
The mercury reservoir is then adjusted to remove all air and the barometer is carried upside down until used again, when it is carefully rotated to an upright position the mercury reservoir slowly adjusted back to its normal operating volume (the PRINCO manual linked below give a detailed proceedure for the modern instrument on display).schoolphysics ::Welcome::Removing air bubbles from a mercury barometer: Motoring Non-motoring forum
