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.

The SVT 15N is an entry level and compact spinning drop tensiometer for measuring
ultra-low interfacial tensions. The drive capillaries can be rotated at up to 17,000
rev/min.
