DataPhysics Instruments, a German company with 25 years of experience, specialises in measurement technology for surface science. We offer a range of devices, which can analyse chemical and physical properties of surfaces and interfaces, such as their interfacial tension, surface energy, work of adhesion, static and dynamic contact angles, roughness profiles, zeta potential and dispersion stability. In short, our products help determining material properties whenever a liquid meets another liquid or a solid surface. In addition to contact angle meters, our portfolio encompasses force and spinning drop tensiometers, dispersion stability analysis systems, surface profile analysers and zeta potential analysers. Services also include high-quality contract measurements in our application laboratories.
