Abstract
An apparatus is provided for identifying each of a predetermined plurality of liquid containers, some of which are stoppered and others of which are open-mouthed and for extracting liquid therefrom. The apparatus comprises an upper arm and a lower arm and a sensor responsive to relative motion therebetween, relative motion between the arms causing a container identity signal representative to be generated. A single needle is used to penetrate stoppers when present and extract liquid from the container.
