Interfacial Shear Rheology


ISR1


In shear rheology the experiments are performed such that the viscosity and elasticity of the interfacial layer are measured. Typical experiments are those using a torsion pendulum, as it is the case in our ISR1. The shear visco-elasticity is an excellent measure for the quantification of structure formations in interfacial layers. The ISR1 is an instrument with a very high sensitivity and is therefore suitable for less dense and rigid layers, where other shear instruments based on forced oscillations cannot be applied.
