The DSA 100 from Krüss Scientific: a modular system for studying wetting and adhesion
The DSA 100 from Krüss Scientific is a high-precision laboratory instrument designed for the detailed analysis of wetting phenomena on solid surfaces. It is a drop shape analyser that not only measures static and dynamic contact angles, but also evaluates complex parameters such as surface tension or surface free energy (SFE). Thanks to its modular design and numerous software and hardware options, the DSA 100 can be tailored precisely to the specific requirements of researchers or industrial quality departments.
At the heart of the DSA 100 is state-of-the-art optical technology that enables fast and accurate image capture of drops deposited on samples. The system is capable of measuring contact angles from 0 to 180° with a resolution of 0.01°, ensuring maximum precision in the analysis of wetting properties. The high-speed camera, capable of up to 3,450 frames per second, provides flawless visualisation even in dynamic environments or during high-frequency experiments.
The system allows analysis of the advance angle, retreat angle and static angle, as well as the rolling behaviour of drops on hydrophobic and superhydrophobic surfaces. In addition, the DSA 100 allows the study of fibres using the meniscus method, as well as the measurement of surface or interfacial tension using the hanging drop method. These features make the device indispensable in fields as varied as coating characterisation, surface cleanliness control and the evaluation of the effectiveness of plasma or corona treatments.
The "Expert" configuration (DSA100E) offers automated positioning on three software-controlled axes, ideal for sequential analyses or surface mapping. This makes it possible to check the homogeneity of wetting or to compare treated and untreated areas of the same sample. This device significantly improves the efficiency of tests in quality control or material development.
Another key feature of the DSA 100 is its compatibility with temperature- and humidity-controlled measurements, with a range from -30 to 400°C. This ability to simulate extreme environmental conditions makes it a valuable tool for the automotive, aerospace and biomedical industries. Its robust design, protective casing and ease of use provide a stable working environment, even in conditions where vibrations could interfere with measurements.
The DSA 100 is much more than just a wetting measurement device. It is a complete, customisable and scalable system that effectively supports surface professionals in their research or industrial quality control operations. With the DSA 100, Krüss offers a high-performance scientific solution that meets the most demanding requirements for surface analysis.
