The spinning drop video tensio­meter SVT 20N is a special purpose optical instrument for measuring extremely low interfacial tensions. This measuring technique offers unrivaled possibilities for the analysis of surfactant effectiveness in the development of emulsions or in the enhanced oil recovery.

The Spinning drop video tensiometer SVT 20N is a compact optical measuring instrument for the determination of low to ultra-low interfacial tensions and rheological interface properties. “Ultra-low” interfacial tensions occur particularly in microemulsions which are used, for example, in enhanced oil recovery.
