Claim Text:
1. A liquid handling device, in particular a syringe pump, for use in a liquid handling system including a plurality of the liquid handling devices assembled in side-by-side relationship at a center-to-center spacing of X, the device including: a barrel, a plunger movable parallel to a longitudinal axis in the barrel for dispensing or aspirating liquid from or into the barrel, an electrically powered motive device for moving the plunger in the barrel for dispensing or aspirating liquid from or into the barrel, and electronics for controlling the motive device and for communicating with an external component, wherein the barrel, plunger, motive device and electronics are assembled together in an envelope having a front portion including at least the barrel and plunger, and a rear portion that is offset along a lateral axis from the front portion and that includes at least a portion of the electronics, wherein the lateral axis is perpendicular to the longitudinal axis, wherein a center plane of the envelope extends along the longitudinal axis and extends parallel to the lateral axis, and wherein the rear portion has a thickness greater than X but no greater than 2X, and the front portion has a thickness no greater than X and is offset relative to the center plane of the envelope along a normal axis that extends perpendicularly from the center plane, whereby the liquid handling device can be assembled with another reversely oriented liquid handling device at a center-to-center spacing of X and a total combined width no greater than 2X.
