Tensiometer K14 – Krüss

A precision instrument dedicated to characterizing the interfacial properties of liquids and solids, ideal for delicate samples such as fibers.

Applications

The K14 tensiometer is ideal for:

  • Studying the wettability of fibers and microstructures
  • Characterizing coatings or surface treatments on thin materials
  • Measuring the surface and interfacial tension of complex liquids
  • Determining the surface energy of fibrous or polymeric materials

 Typical applications:

  • Technical textiles, biomaterials, microfibers, composites
  • Studies of capillarity and liquid/fiber interactions
  • Quality control in formulation and surface treatment

Available Measurement Types

  • Static and dynamic contact angle (advancing and receding) on fibers or plates

  • Liquid surface tension (Wilhelmy method)

  • Liquid/liquid interfacial tension (Wilhelmy method)

  • Surface energy of solids

  • Wettability measurement on small samples, including fine fibers
