The K6 Force Tensiometer is a robust and reliable manual instrument for measuring surface and interfacial tension using the ring tear-off method. As a quality product from our precision mechanical workshop, it performs fast, easy, and accurate measurements for surfactant solutions and solvents. The K6 is also suitable for training purposes for demonstrating the action of the surface tension force in a comprehensible manner.

How the K6 works
The heart of the instrument is a torsion wire which is connected to the measuring ring. The ring is immersed in the sample and slowly pulled out by lowering the liquid. The surface tension (SFT) causes the wire to twist, the deflection of which is shown on a calibrated scale by means of a drag pointer. The pointer moves up to the maximum force and stops after the lamella has been torn off the ring so that the SFT can be read.
