DuNouy Tensiometers

Art. No.: 11495

DuNouy Interfacial Tensiometer

  • Interfacial DuNouy Tensionmeter (dual direction model)
  • Provides precise reading of both surface and interfacial tensions by the ring method to values reproducible within ±0.05 dyne/cm.
  • Graduated dial reads in both directions from zero and a double vernier is provided.
  • Two scales and corresponding verniers have graduations and figures of different colors to indicate whether the measured force is upward or downward.
  • The 6cm ring and its supporting frame are made of platinum-iridium wire and welded.

  • The DuNouy Tensiometers are proven instruments for measuring surface tension quickly, in 15-30 seconds.
  • They are ideal for checking liquids, including oils, detergents, serums, colloidal suspensions, chemicals and other products.
  • Ring method allows readings to be made in 15-30 secs. (Ideal for colloidal suspensions which exhibit rapid changes in surface tension.)
  • Specified for determining interfacial tension of oil against water by the ring method in ASTM Method D971 and solutions of surface-active agents in ASTM Method D1331.
  • Specified for testing synthetic rubber lattices in ASTM Method D1417 and determining the surface tension of industrial water and industrial wastewater in ASTM Method D1590.
  • Circular scale is graduated in dynes/cm eliminating the need for mathematical calculations.
  • Improved technique allows accurate readings to be reproduced within ±0.05 dyne/cm.
  • Compact unit is portable and comes with a carrying case for easy transport.
  • Unit is stable and mounted on a cast tripod support with convenient leveling screws.
  • Surface and interfacial tension measurements are extremely important in the control and improvement of: Absorption, cataphoresis, emulsification, osmotic, ressure, condensation, evaporation, miscibility, solubility

Unit comes completely assembled with torsion wire
6cm ring
