2109944 9222800 PCTABS00018 A liquid dispensing mechanism (34) is provided which includes a dispensing probe having a tip (70) for dispensing liquid, a pump for collectively discharging fluid from the probe tip (70) in measured quantities such as droplets. The dispensing probe has the capability to detect droplet formation and droplet separation from the probe (70) through use of a radio-frequency signal (74, 76) to the probe tip (70) and a conductive element (72) connected to amplifying and analyzing circuitry (78, 80, 82, 84) disposed below the dispensing probe (70) and a reaction well (16) which contains a receiving fluid. The conductive element (72) also detects when the probe has been inserted into the receiving fluid.
