Contact Angle and Surface Energy Measurement

Make and Model:

Kruss DSA30 Drop Shape Analyzer


DSA30 is a robust instrument which can be used flexibly for the precise measurement of contact angle and surface free energy. Measurement of surface tension and liquid-liquid interfacial tension is possible by using the Pendant Drop method.


·   Measuring range

o Contact angle: 1 – 180°

o Surface tension: 0.01 to 1000 mN/m

·   Measurement resolution

o Contact angle: 0.1°

o Surface tension: 0.01 mN/m


·   Characterization of surface pre-treatment processes

·   Investigation of the adhesion and stability of bonding and coating processes

·   Checking the wettability of plastic, glass, ceramic, wood or metal
