Surface Chemistry

The measurement of contact angle, surface tension, surface free energy of solids, work of adhesion and other relevant parameters for surface science is the core competence of DataPhysics from Germany. The tensiometers, contact angle measurement instruments and spinning drop tensiometers are worldwide known in science and industry as high-end instruments.

A broad accessories range for the contact angle measurement devices and tensiometer makes also challenging measuring tasks easy to handle. The measurement of surface tension or contact angle up to 1800°C or under high vacuum together with fast capturing cameras up to thousands frames per sec, unique dosing systems to allow analysis of nano and piko-drops.
Applications : paper coatings, Ink application, cosmetics, Surfactant development, Polymer engineering,  Nanostructured materials, Automobile components, Packaging material,
Electronic components,  Glass coatings, Textile engineering, Agrochemicals,  Bio engineering, & Pharmaceuticals
