ABSTRACT:
Photometric analysis apparatus having a cylindrical glass sample container which is rotated about its axis during optical measurement of sample in the container. Rotation of the 5 container window areas past an optical detector compensates for optical variations and imperfections in the container wall which would otherwise render the measured photometric signal sensitive to each particular rotational orientation of the container.
