An improved nephelometer comprised of a transparent cell for containing a liquid sample, a light source, and a detector is disclosed which reduces the amount of stray light reaching the detector. The cell is characterized in that either the illuminating light beam or the detected light passes through the cell wall face at an acute angle to the normal to the cell wall face.
