An apparatus and method for accurately dosing and dispensing mercury. The apparatus includes a reservoir containing mercury and a capillary tube extending from the reservoir of mercury to a dispensing needle and having an inlet located intermediate a pair of remotely located ends. The apparatus adjusts the height of a column of the mercury within the capillary tube and measures the height of the mercury column. In one embodiment, a digital vision system comprising a TV camera and monitor digitizes the image of the mercury column within the capillary tube and automatically determines the height of the column. A source of gas is supplied to the inlet in the capillary tube such that a predetrmined amount of mercury is separated from the mercury column and dispensed from the other one of the remotely located ends of the capillary tube.
