Getting rid of any user intervention and result interpretation whatsoever, our Ayríís uses groundbreaking technology for perfectly reliable QC checks of wettability. With just one click and in seconds, the 3D Contact Angle of water is measured and auto-validated with a simple passed/failed message using preset quality limits. The highly advanced 3D drop projection technique of Ayríís provides for automatic self-checking of consistency and plausibility of each result. As a mobile, stand-alone instrument with easy-to-exchange rechargeable batteries and prefilled cartridges, Ayríís is prepared to operate 24/7 on your production site.


The RelaxFlow is ideal for use with heterogeneous suspensions where batch sampling is problematic. Use it to monitor milling processes in real time, and under industry-relevant conditions. Also for investigation of the impact of continuous addition of chemical reactants, and for laboratory studies of process control.

MSA measures surface free energy with two liquids, fully automatically and mobile using our new “One-Click SFE” method. The MSA doses two parallel drops with one click, followed by the direct analysis of the contact angles and the derived results of the surface free energy. All steps are automated and happen within a second. The precise measurement and scientific evaluation are performed with a single button click. Thus, measurement errors due to incorrect operation are virtually ruled out.

It is the only instrument in the world to use the top-view reflection method for measuring the contact angle of a liquid on a solid from above. TVA100 determines the contact angle using the radius of curvature of the upper surface of the drop. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the conventional side view. The measuring head is available as a module for the well-proven KRÜSS DSA100, DSA30 and Easy Drop instruments and also as an independent portal system for contact-free measurements on large samples.
