INTERFACIAL RHEOLOGY

ISR-1 Interfacial Shear Rheometer

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.

Interfacial Rheology

ISR-1 Interfacial Shear Rheometer 

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.

Key facts

allows measuring the interfacial shear elasticity and viscosity of layers between two fluids (liquid/liquid or liquid/gas). 

The main principle is a torsion pendulum.

Different measuring bodies are used to work at liquid surfaces or at interfaces between two immiscible liquids.

ISR-1 allows unique shear rheological experiments and is suitable for studies of adsorption layers (GIBBS-layers) and spread layers (LANGMUIR-layers).

frequency range between 0.2 and 0.02 Hz (depending on the measuring body and the torsion wire used)
