A technique is discussed for forming liquid drops of uniform size from a syringe needle. The method is unique in that it employs fluidic technology to produce drops with diameter independent of rate of formation over a wide range of rates. The velocity and placement of the drop after formation are controlled. Drops from 100 to 3000&mgr; in diameter may be produced at rates between 0 and 15 drops per second. Standard deviations of diameter below 1% can be obtained.
