Attension® Sigma Force Tensiometers
Attension® tensiometers offer leading contact angle and surface tension solutions for industrial quality control and R&D as well as for academic research. The core of Attension solutions is a combination of easy-to-use, smart instrumentation with broad surface science capabilities.
Force tensiometers enable precise characterization of a number of material properties. Analysis of surface and interfaction tension, powder wettability, dynamic contact angles, critical micelle concentration, density, sedimentation and adhesion provides valuable information on the interactions between gas, liquid and solid phases. The interaction between these phases plays a key role in studying surfactant development, adhesion, formulation development, absorption, and wettability.
Surface Science Instrumentation
Force Tensiometers employ a simple and robust technique to measure surface tension, interfacial tension and density of liquids. These direct measurements allow determination of a number of material and surface properties, such as dynamic contact angle, surface free energy, critical micelle concentration and wettability.
