Precision measurement should be carried out using a semimicro-quartz glass cuvette (> 350 ┬Ál). Clear and clean solutions are suitable as the measuring medium, for example potassium dichromate (zero adjustment to water) or water (zero adjustment to air). The coefficient of variation (CV) should be smaller/equal to 1% at 1 A in line with the technical data for the BioPhotometer. Please bear in mind that the Secondary UV-VIS filter should be used for exact precision measurement and determination of both the photometric and wavelength accuracy.
