What Is The ARES-G2 Rheometer?

rheometerThe TA Instruments ARES-G2 Rheometer is a mechanical spectrometer capable of subjecting a sample to a Dynamic (sinusoidal) strain deformation, Steady shear strain deformation or Transient test. The ARES-G2 Rheometer measures the resultant torque generated by the sample in response to this shear strain.

 ARES-G2 System Components

  1. Motor.
  2. Stage.
  3. Transducer.
  4. Keypad.
  5. Touch screen display.
  6. Geometries.
  7. Forced convection oven.

What Does a ARES-G2 Rheometer Do?

 ARES-G2 Rheometer measures both viscosity and viscoelasticity of fluids, semi-solids and solids.

It provides information about the materials:

  1. Viscosity: Function of shear rate or stress, time and temperature dependence.
  2. Viscoelastic properties (G', G", tan) with respect to time, temperature, frequency and stress/strain.
  3. Transient response (relaxation modulus, creep compliance, creep recovery).
