Surface tension is a quantitative measure that can be correlated with a solution’s ability to remove dirt.
Surface tension and wettability are important physical properties that play a significant role in the effectiveness of agrochemicals.
Explains three different methods to measure surface tension.
The blog post describes what is surface tension and why is surface tension important in many industrial processes
The method to calculate the surface tension component is defined in ISO 19403-5:2017 standard.
A wetting agent is a surface-active molecule used to reduce the surface tension of water.
Surface tension can be measured with force tensiometer using Du Noüy ring or Wilhelmy plate. Or with optical tensiometer using the pendant drop method.
Du Noüy method utilizes the interaction of a platinum ring with the surface of the liquid.
The surface tension of water is about 72 mN/m at room temperature which is one of the highest surface tension for liquid.
