ABSTRACT:
An improved pipette device for removing and transferring a plurality of liquid samples to and from a multi-well tray is disclosed. The pipette device comprises the housing having an elongated plate defining a first chamber therein. A patterned array of collector conduits are joined to the plate such that a first outwardly extending section extends into the chamber and a second outwardly extending section, in flow communication with the first, extends away from the chamber and toward the tray. A port is formed on the housing such that a vacuum can be created in the first chamber whereby a predetermined quantity of liquid is caused to flow into each of the collector conduits. The conduits are designed to contain decreasingly smaller volumes to allow precise measure of the contained volume when the conduits are filled.
