The entry level instrument which is an easy-to-use and reliable for measuring contact angle, Surface Free energy and Surface & Interfacial Tension measurement by Pendent drop method.

The trend to water-based bonding, coating and printing on plastics has made solving wetting problems an important challange, With the DSA25, KRUSS covers the increasing demand for rapid wetting tests.
