An apparatus and method for dispensing a predetermined volume of liquid from a closed, liquid-containing blood collection tube is described. The apparatus includes a dual conduit providing a passageway for liquid to be dispensed from a closed blood collection tube and a gas conduit providing a passageway for gas to be introduced into the blood collection tube. Included in the apparatus is insertion of the dual conduit into the blood collection tube, turning the tube away from a vertical, upright orientation, connecting and disconnecting the gas passageway from a gas supply, displacing a volume of gas through the gas passageway, and controlling the operation of the apparatus. A method is also disclosed involving insertion of a dual conduit into a closed blood collection tube, connecting a gas supply to a gas conduit of the dual conduit, rotating the tube away from a vertical, upright orientation, introducing a volume of gas corresponding to a signal into the blood collection tube, receiving a predetermined volume of liquid from the blood collection tube, and physically disconnecting the gas supply from the gas passageway.
