Contact Angle Goniometer

Description:

The FTA32 goniometer provides video-based contact angle and surface tension measurement. Contact angles are measured by fitting a mathematical expression to the shape of a drop and then calculating the slope of the tangent to the drop at the liquid-solid-vapor (LSV) interface line. Computer software drop shape analysis gives contact angle without operator intervention or judgement.

Scientific Opportunities / Applications:

  • Contact angle measurement 
  • Surface tension calculation 
  • Liquid drop shape analysis

Access Information:

Access to this tool requires that you have attended NanoFab safety orientation, passed the safety test, and have been properly trained on the tool. If you have any questions, please contact the NanoFab User Coordinator, or the tool contact person.
