DU NOUY INTERFACIAL TENSIOMETER
The Du Nouy Ring Method is the best known method for measuring the surface tension of liquids. A platinum-iridium ring is placed into the liquid, and then slowly pulled out so that a lamella is formed at the air interface. The force needed to pull this lamella is a direct measure for the surface tension of the liquid.

This method is particularly suitable for comparing the surface tensions of aqueous solutions of various surfactants, or of clear solventborne coatings. 
With the Interfacial Tensiometer, the ring is attached by insertion in to a sleeve, which allows the ring to measure with both upwards and downwards pull.
