Contact angle and surface tensiometry

Contact angle measuring device for the measurement of the static and the dynamic contact angle, the surface free energy of solids, and the surface and the interfacial tension of liquids.

The OCA 20 enables the reduction of subjective factors and time involved for contact angle measurements in research, quality and production inspection.

It is easy to use. The video-based optical contact angle measuring system OCA 20 is the most versatile instrument for the contact angle measurement and drop shape analysis.


  • Maximum sample size (LxWxH): 22 x 22 x 7 cm
  • Range of contact angle measurement: 0 to 180° ; ± 0.1° measuring accuracy of the video system
  • Range of surface and interfacial tension 1x10-2 to 2 x103 mN/m; resolution: min. ± 0.05 mN/m


We can train you to do your own work, collaborate or do consulting work (fee for service).
For trained users the Cypher is available on the MCFP's iLab Booking System. For new users to this instrument, please contact Tian to arrange training.
