Contact angle analysis

Testing and validation > Topological Analysis and Surface Profiling


Observing the contact angle of a liquid on a samples surface can be a simple way of determining a samples hydrophobicity.

To measure this many contact angle analysers use a high resolution camera to take an image, then use specific software to interpret the photo and provide the angle of contact. It is...
