Spinning Drop Video Tensiometer SVT 25
To best illustrate the actual working environment, the cell temperature is controlled between -30 °C and 180 °C. Besides that, the SVT25 can also measure aqueous solutions at temperatures up to 130 °C when high-pressure capillaries are in use.
The compact optical Spinning drop video tensiometer SVT 25 is an instrument for the determination of low to extremely low interfacial tensions (such as microemulsions in enhanced oil recovery (EOR)) as well as rheological interfacial features.
Due to a well-established measurement technique along with first-class optical and mechanical components, the obtained data are guaranteed with high accuracy and reproducibility. The SVT 25 operates through the TP 50 control panel, which is made up of sophisticated electronic parts.

Operators can move the analyzed droplet into the camera’s field of view, where a lens with up to 6.5x zoom is available for sharp images regardless of whether it’s a large or small drop. The processes are easy as the measuring cells and rotating capillary wires are mounted on an inclined table, increasing measurement efficiency.
