Patent ID: 7083117

Claim:
A system for altering a trajectory of a droplet comprising: a droplet generator; a coupling medium adapted to be disposed on a distal portion of the droplet generator, wherein the coupling medium is further adapted to at least partially conform to a bottom surface of a wellplate while transmitting acoustic energy generated by the droplet generator into the wellplate to eject said droplet; and a structure having a passageway for said droplet of liquid to pass through after ejection, wherein said structure comprises a throated structure having a nozzle defining said passageway with an entrance port at a proximal end of the nozzle and an exit port at a distal end of the nozzle, wherein the throated structure further defines at least one channel in fluid communication with the nozzle for receiving a gas stream such that the trajectory of a droplet entering the entrance port is alterable by said gas stream to a predetermined path as the droplet passes through the exit port.
