Dynamic Contact Angle & Surface Tension Analyzer

Dynamic

DCA-200 Analyzer from Surface Electro Optics, specifically designed to record dynamic advancing and receding contact angle. Dynamic contact angle measurements can provide important insight into the nature of surfaces, surface reactivity, surface topography, homogeneity and porosity, and surface treatments required for bonding and adhesion.

The DCA can measure the surface tension of a liquid. The information of the surface tension is critically important in applications such as detergency and emulsification and is also important for many biological processes.
