An ultra small quantity fluid dispenser having a needle like dispense tip terminating in an orifice is provided with an interior lumen diameter increasing counterbore at the orifice to reduce wicking of fluid being dispensed. A wicking wire may be positioned in the lumen extending from the orifice, the wire having a smaller diameter than the lumen resists wetting of the exterior of the nozzle tip by fluid being dispensed by the orifice.
