Contact angle

Contact angle

Contact angle analysis is used to quantify the wettability of a solid surface by a liquid.

The contact angle is defined as the angle where the liquid-vapor interface meets a solid interface. This equipment provides the capability to study the wetting of a liquid on a surface through the accurate measurement of the static or dynamic contact angle. Automatic measurement sequencing and video processing allow reliable, fast and reproducible results to be obtained on simple or complex samples. From the polar and dispersive components, we can determine the surface chemical nature of a coating or material (hydrophilic, hydrophobic, super-hydrophobic, oleophilic, oleophobic).
