Contact Angle Measuring Instrument OCA 200

For software-controlled measurement and analysis of

  • the static and dynamic contact angle according to the Sessile & Captive Drop method
  • the geometry of hanging drops using the pendant drop method
  • the wetting behaviour on solid surfaces
  • the surface free energy of solids and their components
  • the surface and interfacial tension from the drop shape analysis
  • the advancing and retreating contact angle as well as the roll-off angle of horizontal drops
