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.
