Abstract
A nephelometer that measures turbidity of low volume suspensions using measurements of light transmitted through and/or scattered by the sample. The sample suspension is placed in a tiered cuvette adapted to facilitate measuring the turbidity of low volume samples. The lower portion of the cuvette has smaller dimensions, in horizontal cross section, than the top portion. Both lower and upper portions have angled surfaces. The lower, smaller portion of the cuvette is interrogated by the nephelometer.
