Waters Corporation launches the ARES-G3 Rheometer, a next-generation instrument designed to accelerate materials characterization while delivering high-resolution data. Part of the company’s TA Instruments portfolio, the ARES-G3 Rheometer captures up to 25,000 data points per second and reduces standard testing times by as much as 80%.
The system addresses challenges faced by rheology laboratories that require deeper insight into complex and rapidly changing material behavior. The instrument enables measurements of fast-changing samples within a single test and supports higher laboratory throughput through shorter experiment times.
“Rheology labs are under enormous pressure to deliver better data, faster, to unlock breakthroughs and support business decisions,” remarks Dan Rush, Senior Vice President, Waters Materials Sciences, Waters Corporation. “We're pleased to deliver a cutting-edge instrument that can provide unique data in record time, providing novel insights and empowering our customers to meet these increasing demands.”
The ARES-G3 Rheometer captures up to ten times more data points per second than its predecessor. The instrument integrates Fast Frequency Chirps directly within enhanced TRIOS™ Software, allowing rapid frequency sweeps without requiring multiple software licenses or advanced programming tools.

This integration enables faster routine testing and streamlined workflows. Under typical conditions, some quality control tests that previously required six hours can now complete in approximately one hour. These time savings can translate into hundreds of workdays saved annually for laboratory teams.
The rheometer also reduces the need for user calibrations. Fewer calibrations decrease the risk of human error and increase confidence in measurement results.
Researchers studying fast-evolving materials often struggle to capture critical data during curing or degradation processes. According to Chris Macosko, Ph.D., Professor Emeritus in the Department of Chemical Engineering and Materials Science at the University of Minnesota, the instrument addresses this limitation. “For years, rheologists have struggled to capture in-depth data on materials that are actively curing or degrading," advises Macosko.
The kinetics are so fast that conventional rheometers miss the critical information. Integrating Fast Frequency Chirps and precise temperature control means we can now generate time-temperature-dependent data in one-fifth of the usual time. The new ARES-G3 Rheometer delivers the accurate and consistent data that we need to succeed.”
The instrument builds on the legacy of the ARES-G2 Rheometer while introducing several updates. A new touchscreen improves at-instrument control, while hardware and software upgrades enhance data capture. The system maintains proprietary dynamic mechanical analysis capabilities and dedicated hardware for both stress measurement and strain control.
The rheometer also retains the oven design from the ARES-G2 Rheometer. This design provides low-oxygen atmosphere control and temperature uniformity, allowing researchers to simulate real-world processing conditions and study structure-property relationships. Existing ARES-G2 methods and fixtures remain fully compatible with the ARES-G3 Rheometer.
