Drop Shape Analyzer Drop Shape Analyzer – DSA25E (Expert configuration) The basic instrument for wetting investigations Our Drop Shape Analyzer – DSA25 is an easy-to-use, reliable instrument for measuring contact angle. From a simple wetting test to the accurate measurement of surface free energy (SFE), the robust instrument provides flexible options for analyzing wetting and adhesion on solid surfaces. Its rapid, manual sample positioning makes the DSA25 outstandingly suitable for occasional wetting measurements with changing tasks and sample types. Measuring methods and options ■ Characterization of surface pretreatment processes ■ Checking the wettability of plastic, glass, ceramic, wood, ■ Contact angle between a liquid and a solid ■ Surface free energy from contact angles of several test liquids ■ Validating surface cleanliness ■ Static contact angle, advancing angle, and receding angle ■ Measurement of surface tension and liquid-liquid interfacial using all common models tension using pendant drop or constrained sessile drop ■ Temperature-controlled measurements from -30 to 400 °C ■ Measurements at controlled humidity ■ Measurement

Reliable drop shape analysis thanks to high imaging quality The DSA25 features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. The high image quality that this achieves leads to a precisely measured contact angle or surface tension. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.
