Drop Shape Analyzer - DSA25E - Krüss
Optimized for High-Speed Wettability Analysis - Krüss DSA25E
The Krüss DSA25E Drop Shape Analyzer, in its Expert configuration, is engineered for precise determination of the wettability of solids through contact angle measurement and for assessing the surface tension of liquids, including adhesive and coating substances. This advanced instrument combines speedy analyses with a broad range of evaluation options, offering rapid feedback on pretreatment processes in quality control contexts and allowing for a thorough examination of resulting adhesion.
Applications and Measuring Techniques
This versatile tool serves a wide array of applications, from quality assurance in activation processes (like plasma, flame, or corona treatment) to the evaluation of the wettability of various materials (plastics, glass, ceramics, and more) and the effectiveness of hydrophobic coatings. It also excels in analyzing surface chemistry of coatings and adhesives, assessing adhesion, and conducting wetting analysis at controlled temperatures or humidity levels.
Advanced Features for Comprehensive Analysis
The Krüss DSA25E boasts a high-resolution camera and quality optics, ensuring precise measurements of contact angles or surface free energy (SFE) within seconds, courtesy of its innovative Liquid Needle technology. Its ADVANCE software facilitates automated measurements, enhancing repeatability and allowing for comprehensive adhesion analysis alongside additional scientific parameters. Ideal for applications requiring rapid and reliable surface chemistry assessments, the DSA25E sets the standard for quality and efficiency in surface analysis.
