You searched for: Nessler Tubes

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.
