— A calibrated volumetric optical cuvette is described which both simplifies the technique and improves the precision of potassium ferrioxalate actinometry. The cuvette is used both for irradiation of the actinometer solution and for in situ dilution and chemical developing of the irradiated aliquot. The technique permits all but one manipulation to be carried out in total darkness, thus protecting the actinometer solutions from ambient light. The method can be extended to any actinometric procedure and the volumetric cuvettes are very useful in a variety of other spectrophotometric applications.
