The KRUSS K6 Force Tensiometer is a robust and reliable manual instrument for measuring surface and interfacial tension. It performs fast, easy, and accurate measurements of 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.
Simple operation
The heart of the instrument is a Pt torsion wire which is connected to the measuring Pt-Ir 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.
