Surface Tension measuring instruments

 

Surface tension is a property of the surface of a liquid that allows it to resist an external force. We come across many applications of Surface Tension in our daily life like the use of detergent, soap,shampoo, creams, branded juice, soft drink, bear, pharmaceutical suspensions, printing, writing, printingetc are some common process, where Surface Tension has an importantrole to play. The formulator needs to use various Surfactants in order to develop a product which meet users expectations and are cost effective. They need to optimizethe quantity of various surfactants in order to minimize/ maximize the Surface tension. There are different methods in use for the measurements of Surface Tension, which can be broadly classified as follows:


Static measurements:

  • Du Nouy Ring Method:The traditional method used to measure the Surface or Interfacial Tension. Maximumpull exerted on ring bysurface is measured.

 

  • Wilhelmy Plate Method: A vertical plateof known perimeter is attached to a balance and the force due to wetting is measured.

 

  • Rod Method:A Pt- Rod is used to measure the surface tension by measuring the change in weight with respect to time due to wetting.

 

  • Spinning Drop Method:The method is used for low IFT, the diameter of drop within a heavy phase is measured with rotation of both the phases.

 

  • Pendent Drop Method:Surface and Interfacial Tension canbe measured by this technique, even at elevated temperature and pressure. Geometry of a drop is analyzed optically.


Dynamic Method:

 

  • Bubble Pressure Method:A measurement technique for determining Surface tension at short ages, maximum pressure of each bubble is measured.

 

  • Drop Volume Method:A method for determining interfacial tension as a function of interface age, liquid of one density is pumped into the second liquid of a different density and time between drops produced is measured.

A speedometer for surfactants

You know just how effective your surfactant is. But do you also know how quick it is?
Whether pumping, stirring or flooding: oil-water interfaces are always in motion. Just knowing the equilibrium value of the interfacial tension is no longer sufficient. The drop volume technique of the DVT50 from KRÜSS records the interfacial tension under dynamic conditions – in an interface age ranging from fractions of a second up to several minutes.
Thanks to its wide measuring range from 100 mN/m down to 0.1 mN/m and the possibility of thermostatting the liquid phases the instrument is suitable for a wide range of applications. Very simple handling during filling and cleaning as well as software control with programmed measuring sequences ensure a smooth measurement procedure with a high sample throughput.

 

Application:


  • Emulsification in cosmetics, pharmaceutical and food industries

  • Tertiary crude oil recovery

  • Solvent-free degreasing

  • Cleaning processes

  • Liquid explosives
