Spinning Drop Tensiometer Measurement of interfacial tension in an extremely wide range with especially simple sample exchange Our Spinning Drop Tensiometer – SDT measures interfacial tension with a high degree of accuracy and a particularly wide measuring range. The SDT is the ideal solution for the quality control and development of emulsions and surfactants thanks to its enormous bandwidth, small sample volumes, and simple handling during preparation. Exact capture of extremely low interfacial tensions also makes the SDT an instrument particularly well-suited for analyzing the interfacial behavior of miniand micro-emulsions, for example for tertiary oil recovery or the pharmaceutical industry. Measuring methods and options ■ Development of emulsions ■ Enhanced oil recovery (EOR) ■ Bioavailability of drugs ■ Surfactant research ■ Adsorption properties at phase boundaries ■ easurement of interfacial tension in a wide range down M to 10-6 mN/m ■ Analysis using the drop diameter according to Vonnegut ■ Analysis using the drop shape curvature according to Young-Laplace ■ Long-term measurement for analyzing surfactant dynamics ■ Temperature

Exact rotation, image evaluation, and drop positioning A high-resolution camera and a motor with excellent speed constancy are among the most important components of the instrument, combined with the intelligent image evaluation algorithm of the software ADVANCE. The previously necessary observation of a running measurement is now obsolete, as the drop can be automatically held in the middle of the video image. Patented capillary concept for quick sample exchange SDT with tilted measuring unit Innovations for quick sample preparation Putting a drop inside the filled capillary used to be a...
