High-performance rotational viscoelasticity measurement device ARES-G2 rheometer
ARES-G2
Independent measurement of stress and strain is possible! Introducing the rotary viscoelastic measurement device/reometer ARES-G2, equipped with excellent features.
The "ARES-G2" is an advanced rotational viscoelastic measurement device/ rheometer for research and material development. It is equipped with dedicated actuators for deformation control for independent shear stress and normal stress measurements, as well as a torque balance transducer (TRT) and a force balance transducer (FRT). It allows for measurements free from device-induced effects across a wide range of stress, strain, and frequency. 【Features】 ■ Excellent data accuracy ■ Superior strain and new stress control ■ Fully integrated high-speed data sampling ■ Isolated power supply ■ New Smart Swap environmental system

Oscillation Frequency Sweep Temperature and strain are kept constant during the frequency sweep, and the viscoelastic properties are monitored as the frequency changes. This figure explains the viscoelastic characteristics of linear homopolymers and shows the changes in G’ and G” as functions of frequency. Since frequency is the inverse of time, the curve demonstrates the time-dependent mechanical response to short times (high frequency) resembling solid-like behavior, and to long times (low frequency) resembling liquid-like behavior.
