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.
