Turntable device for analyzing chemical substances

摘要

The present invention concerns a device for analyzing chemical substances and monitoring chemical reactions in which cuvettes on a turntable are rapidly scanned by light at test and reference wavelengths and intensity of the light after passage through the cuvettes monitored by a photodetector. The output of the photodetector is logically processed so that measurements can be made of the varying optical densities in the samples scanned.
