Interfacial Shear Rheometer ISR-1

Measures shear rheology after torsion pendulum principle
This instrument allows measuring the interfacial shear properties of layers between two fluid (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. The ISR-1 (Interfacial Shear Rheometer) from SINTERFACE allows unique shear rheological experiments.
ISR-1

Instrument parts
mechanical and electronical unit
temperature controlled measuring cell
data acquisition via RS-232

The instrument allows the following measurements

  • frequency range between 0.2 and 0.02 Hz (depending on the measuring body and the torsion wire used)
  • shear elasticity and viscosity of a surface layer
  • time resolution about 1 minute
  • time dependencies over hours of adsorption time
  • surface shear viscosity range 1 µNs/m to 100 mNs/m
  • surface shear elasticity range 1 µPam to 100 mPam
  • temperature control in the range 10 to 50 °C
