Product Overview

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.

Benefits

  • Manual tensiometer for rapid, simple & user-friendly operation
  • Measure surface tension and interfacial tension using the ring method
  • Instrument is supplied with Pt-lr ring and a vessel
  • Result of the measurement is indicated accurately to 0.5mN/m
  • Ideal as a teaching or training tool for demonstrating the action of surface tension

Applications

The KRUSS tensiometer range has acquired a great reputation for reliability in investigating surface tension and interfacial tension of liquids. The KRUSS tensiometer has become indispensable in labs that require accurate analysis of emulsifying agents soaps, wetting agents and to indicate the presence of oxidation and polymerisation in fats, organic oils and fuels.

K6 can be used for:

  • Quick and accurate measurements for surfactant solutions and solvents
  • Simple investigations of liquid and liquid-liquid interfaces
  • Ideal as a teaching or training tool for demonstrating the action of surface tension
