Interfacial Tension Test using a Du Nouy Ring

WebAug 25, 2024 · As its connecting method of surface tensiometer made by other manufacturers (such as Kruss or Dataphysics) is fixed method, while height of the probe for measurement of surface tension/contact angle usually varies so much, in which situation, larger travel range such as 110mm must be adopted. WebTo measure the surface tension between a liquid and the air, the duNouy ring is placed below the surface of the liquid. This test is performed by pulling the ring upward through the surface of the liquid. The force needed for the ring to break the surface (overcome the surface tension) is determined. This measurement is in dynes/centimeter.
