Surface Energy Analyzer

Contact angle measurement is a characterization method of surface analysis related to surface energy and surface tension between a solid and a liquid drop. Contact angle describes the shape of a liquid drop resting on a solid surface and is defined as the angle between the tangent line (drawn from the drop shape to the touch of the solid surface) and the solid surface. The measurement provides information to study the bonding energy of the solid surface and surface tension of a liquid droplet.
