The wetting properties of common solids can be measured with electronic tensiometers which has been evolved to dynamic contact angle meters. The ease of use in providing highly reproducible results with these instruments has been achieved by extensive application of internal and external computer control.

In addition, instruments such as the tensiometers DCAT 11EC, DCAT 11, or DCAT 21 provide a very high level of automation in the determination of wetting properties exhibited by powders, fibers, and  fabrics as well as the thermodynamic properties of surfactant solutions.

The spinning drop video tensiometer SVT 20N is a special instrument for measuring high to extremely low interfacial tensions. It is featuring the optical technology of the contact angle video-based measuring instruments from DataPhysics. In a compact design, the SVT 20N is intended to supersede the traditionally manual operation of these tensiometer systems.

With the additional feature of video contour recognition and evaluation technology, an important  contribution can now be made to research in raw materials for emulsions, encapsulated drops, and tertiary oil recovery to the advantage of product quality and the preservation of the environment.
