Nessler tubes are used for comparison of colour and turbidity between solutions. They are available in tall or short form, and the tubes are often used to carry out a series of calibration solutions of increasing concentrations, meaning they can function as a comparative scale. To minimize differences in the subjective impression of the colour of the substance to be analysed, cylinders of a series should have the same characteristics—height, diameter, and glass thickness.
