Goniometer DSA100 – Krüss

The DSA100 goniometer is a precision instrument designed for analyzing wetting properties and surface tensions. It measures contact angles between a liquid and a solid surface, as well as surface and interfacial tensions of liquids, across a wide temperature range.

Applications

The DSA100 goniometer is used to :

  • Assess surface wettability (hydrophilic or hydrophobic character)

  • Monitor the quality of surface treatments (plasma, coatings, grafting)

  • Optimize adhesion of adhesives, paints, inks, or varnishes

  • Characterize technical materials (superhydrophobic coatings, textiles, membranes)

  • Measure surface or interfacial tension during the formulation of complex liquids (cosmetics, inks, detergents)

Available Measurement Types

  • Static and dynamic contact angles (advancing / receding)

  • Roll-off angle on hydrophobic surfaces

  • Surface tension (pendant drop method)

  • Interfacial tension (liquid/liquid)

  • Surface energy calculation of solids

  • Measurements under controlled temperature : from -20 °C to 400 °C
