Drop shape analyser

Model : DS25B

Brand : KRUSS

The drop shape analyser is used for wetting and adhesion analysis. The instrument can be used to determine the contact angle between a liquid and a solid and also to measure surface free energy. It is especially useful for the analysis of cleaned, pre-treated or coated solid materials.

Tasks and Applications

  • Characterization of surface pre-treatment processes
  • Testing of the wettability of plastic, glass, ceramic, wood, paper, textiles or metal
  • Testing of surface cleanliness

Measuring methods and options:

  • Contact angle between a liquid and a solid
  • Surface free energy from contact angles of several test liquids using all common models
  • Static contact angle, advancing angle and receding angle
  • Temperature-controlled measurements from -30 to 400 °C
  • Measurements under controlled humidity
