Surface tension with the ring method (Du Nouy method)

Article No: P2140500

The force is measured on a ring shortly before a liquid film tears using a torsion meter. The surface tension is calculated from the diameter of the ring and the tear-off force.

Key Features

High sensitivity measurement possible thanks to ring method
Analogue set-up that can also be used as a demo experiment in the lecture hall
Torsion dynamometer used can measure very small forces and is therefore suitable to measure other electrostatic and magnetic interactions between bodies
