Tensiometer K12 – Krüss

A versatile device for precise analysis of surface and interfacial tensions, suitablefor liquids, solids, and powders alike.

Applications

The K12 tensiometer is designed to :

  • Evaluate the interfacial properties of liquids and mixtures
  • Characterize the wettability of solids, including powders
  • Determine surfactant performance (surface tension, CMC)
  • Monitor the uniformity of surface treatments
  • Study capillarity and absorption in porous media

Available Measurement Types

  • Static and dynamic contact angle (advancing and receding)

  • Surface tension (liquid/air) – Wilhelmy method (plate or ring)

  • Interfacial tension (liquid/liquid) – Wilhelmy method

  • Surface energy of a solid

  • Critical micelle concentration (CMC)

  • Liquid density (using brass cylinder)

  • Powder measurement by Washburn method (capillary absorption)
