Surface tension measurement by Du Noüy ring method

In surface science, the du Noüy ring method is a technique for measuring the surface tension of a liquid. The method involves slowly lifting a ring, often made of platinum, from the surface of a liquid. The force, F, required to raise the ring from the liquid's surface is measured and related to the liquid's surface tension, γ: See more • Sessile drop technique • Wilhelmy plate See more • Video showing a classical torsion wire du Noüy tensiometer • Picture of a classical torsion wire du Noüy tensiometer (National Institutes of Health) See more WebFamily Part #: ASGE TSI-70545000-1.
