The DataPhysics OCA 20 is a fully automatic image capture system, in addition to contact angle measurements, it can calculate the surface and interfacial tension of liquids by means of a pendant drop method or for high-viscous materials by use of a Lamella method. The main advantage being its relative ease and quickness of operation.
Contact angle measurements are useful for wettability and surface free energy estimations on a range of solid surfaces. These studies are important to a number of industries including painting, printing, adhesive bonding, polymer processing and manufacturing. A commanly used method is the sessile drop technique to study wettability. In addition, advanced and receded contact angles can be measured and the difference between these, the hysteresis, can give an indication of surface chemical heterogeneity and roughness.
