Surface properties of liquid and solid materials can be measured by many different techniques. Among those surface properties, surface tension of liquid, surface free energy of solid, liquid-liquid and solid-liquid interaction characteristics are of most interest.

Thermo Cahn Dynamic Contact Angle analyzers (DCA) are instruments that are using the Wilhelmy plate theory to obtain the above information about solid, liquid, and solid-liquid characteristics. With the highly integrated and sophisticated hardware and software, Thermo Cahn DCAs offers a powerful, and versatile approach to the comprehensive understanding of the complex interactions at liquid-liquid and liquid-solid surfaces.
