Advanced Drop Shape Analysis for Surface Science
The DSA100 Drop Shape Analyzer – DSA100S from Krüss presents a top-tier semi-automatic measurement solution for both static and dynamic contact angle analysis, crucial for scientific evaluation of wettability through surface free energy (SFE) determination. Its robust design makes it exceptionally suitable for reliable quality assurance of surface pre-treatment techniques and for the development and optimization of various wetting and coating processes. The instrument is enriched with accessories enabling ultra-fast one-click SFE measurement and specialized analysis at elevated temperatures, broadening the application range significantly.
Key application areas include optimizing activation processes like plasma, flame, or corona treatment before bonding or coating, understanding the wettability of various materials including plastics, glass, ceramics, and metals, evaluating the efficiency of hydrophobic and other types of coatings, analyzing surface cleanliness, and conducting wetting analysis under controlled temperatures.
DSA100S heralds advanced measuring methods, including contact angle measurements on solid surfaces and using a gas bubble, analyzing contact angles for two drops dosed in parallel, and determining the surface free energy of solids. The robust housing minimizes vibration impact, while software-controlled dosing ensures precision and reproducibility. The high-resolution camera and quality zoom lens work in tandem with the ADVANCE software for precise, user-independent results.
