Separate Motor and Transducer (SMT) Technology

The ARES-G3 Rheometer’s SMT design sets a new benchmark in precision by decoupling the motor from the measurement, eliminating common calibration protocols and uncovering nuanced material behaviors that standard systems often miss. This independence is especially valuable for high-fidelity deformation testing like large amplitude oscillatory strain (LAOS), and for evaluating soft or complex materials such as emulsions and polymers under challenging conditions.

At the core of SMT lies the force rebalanced transducer (FRT), which stays motionless and captures the sample’s true response with minimal disruption from motor dynamics. When paired with the powerful drive motor, it delivers cleaner data free from typical mechanical noise, giving researchers greater confidence in their rheological insights.

Revolutionizing Rheology with Fast Frequency Chirps Technology

New optimally windowed chirps (Fast Frequency Chirps) technology¹ as integrated in TRIOS Software transforms rheology frequency sweeps by dramatically boosting speed and data density, especially at low frequencies. Fast Frequency Chirps enables ramped time temperature superposition (TTS) master curves generation in under an hour, replacing multi-hour tests without compromising accuracy.

Unlike traditional single-frequency methods, Fast Frequency Chirps’ rapid sweeps track fast-changing systems like curing or chemical reactions, making it ideal for polymers, thermosets, and composites. Fully integrated into TRIOS Software, Fast Frequency Chirps streamlines workflows with automated analysis, delivering faster, high-quality results with ease.

Enhanced Measurement Capabilities

Rheology matters most when it reflects real-world performance. The ARES-G3 Rheometer simulates a wide range of conditions, from temperature shifts to force and pressure, so materials can be designed and tested with confidence and precision.

Environmental
