Drop Shape Analyzer Drop Shape Analyzer – DSA30E (Expert configuration) Contact angle measurement in quality control The Drop Shape Analyzer – DSA30 is a robust instrument which can be used flexibly for the precise measurement of contact angle and surface free energy (SFE). With high-quality components and various automation options, the DSA30 analyzes wetting and adhesion on solid surfaces. Fast measurements and simple operation make the instrument a valuable part of your routine quality control. Measuring methods and options ■ Characterization of surface pretreatment processes ■ Investigation of the adhesion and stability in bonding and ■ Contact angle between a liquid and a solid ■ Surface free energy from contact angles of several test liquids ■ Checking the wettability of plastic, glass, ceramic, wood, ■ Static contact angle, advancing angle, and receding angle ■ Surface tension and liquid-liquid interfacial tension using coating processes or metal ■ Validating surface cleanliness using all common models pendant drop or constrained sessile drop ■ Measurements on inclined surfaces ■ Temperature-controlled measurements from -30 to 400 °C ■ Measurement

Automated positioning for complete sample analyses The DSA30 can be fitted with three software-controlled axes. These move the sample accurately and quickly to all programmed measuring positions. This makes it possible to carry out complete, standardized analyses, which is ideal for quality control. Moreover, wetting can be analyzed dependent on the sample position to check for homogeneity or to assess differences between coated and uncoated areas, for example.
