Abstract: A vertical beam spectrophotometer for measuring the light absorption of an assay prepared using standard wet chemistry procedures and conventional solid phase coated bead technology is disclosed. The spectrophotometer measures the absorption of the assay in a conventional reaction cuvette with the bead remaining in the cuvette. The light source of the spectrophotometer illuminates the bead, which diffuses the light into the surrounding assay solution. A lense projects the diffused light onto a photocell which converts it into an electrical signal having magnitude related to the light absorption of the assay. The signal is processed in a known manner by conventional processing circuitry to obtain an absorption value.

Abstract: 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.
