DataPhysics - SVT - Spinning drop video tensiometer

The spinning drop video tensiometers of the SVT series are special-purpose optical instruments for measuring extremely low interfacial tensions and rheological properties. This measuring technique offers unrivalled possibilities for the analysis of surfactant effectiveness in the development of emulsions or in the enhanced oil recovery.

Key features

  • Measurement of low to ultra-low interfacial tensions based on the contour of spinning drops according to models by Vonnegut, Cayias-Schechter-Wade or Young-Laplace
  • Highly dynamic measurement drive with 0 … 20000 rev/min
  • Oscillation measurements with oscillation periods of 0.5 s …∞ and max. acceleration of 500 rev/s2
  • Motorised tilting table
  • Fast 6.5-fold zoom lens with integrated continuous fine focus
  • Motorised movable optics for automatically following moving drops
  • High-performance camera with USB 3 interface, 2/3″ sensor, max. 2048 x 1088 pixel, max. 3250 frames/s
  • Precise, fast and easy to use capillary exchange system
  • LED-lighting with strobe function and adjustable slit diaphragm
  • Temperature controlled measuring cells for temperatures ranging from -30 °C to 180 °C
  • Sspecial capillary for measuring water-based solutions at up to 130 °C
  • Automatic calibration function for correcting optical distortions caused by the capillaries (cylindrical lens effects)
  • TP 50 control panel with touch screen and precision control wheel
