Interfacial Shear Rheometer (ISR)

The KSV NIMA Interfacial Shear Rheometer (ISR) is an advanced characterization instrument for studying the viscoelasticity of Langmuir films. It is used for studying phenomena that are controlled by interfacial viscosity and for studying the properties of the films prior to deposition to determine the optimal deposition parameters.
