DuNouy Tensiometers
Article No. 11494
DuNouy Precision Tensiometer
- Precision DuNouy Tensiometer (upward direction model)
- Provides precise readings of upward interfacial and surface tensions by the ring method to values reproducible within ±0.05 dyne/cm.
Features
- 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
