Objective: Measure the surface tension by the “breakaway” method
To determine the surface tension of a liquid, a blade is immersed horizontally in the liquid and is slowly pulled out upwards while measuring the pulling force. The lamella of liquid that forms at the blade “breaks away” when the force exceeds a certain value. From this force and the length of the blade one can calculate the surface tension.
