Abstract

A single channel reformatter having a syringe that is movable along a z-axis by a z-positioner. A x-y positioner is capable of positioning any well of a source plate having a plurality of wells, and of positioning any well of a destination plate having a plurality of wells, beneath the syringe. Liquid from a well of the source plate is aspirated by the syringe and dispensed into one or more wells of the destination plate. Since the syringe does not move in the x-y plane, it is advantageously integrated into a wash system that cleanses it between liquid transfer operations. The drive element that actuates the syringe to aspirate and dispense during liquid transfer operations is advantageously used to drive the wash cycle. In a method according to present invention for controlling the reformatting operation, well-to-well links are specified, a preferred execution order for executing the specified links is determined, and the specified links are executed in the preferred order.
