US Classification:

4174101

Abstract:

Provided is a liquid handling device 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 includes a barrel, plunger, motive device and electronics assembled together in an envelope having a front portion including at least the barrel and plunger, and a rear portion including at least a portion of the electronics. 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 laterally offset relative to a center plane of the envelope, 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.

Abstract:

An inert linear shear valve is presented for fluidly coupling at least two flow passages. The linear shear valve includes an actuation device () that moves a sliding plate () to a position where the at least two flow passage () are fluidly coupled. The sliding plate () is biased towards a manifold () containing the flow passages () by at least one resilient member () housed in a carrier (). The sliding plate () has a minimal contact area with the manifold to minimize wear of the sliding plate ) and the manifold ().
