The TA Instruments AR 2000ex Rheometer is a high-performance rotational rheometer designed to measure the flow and deformation behavior of materials under controlled stress, strain, and shear conditions. It is widely used for advanced rheological characterization of liquids, polymers, gels, pastes, and semi-solid materials.
The system features a low-inertia drag-cup motor, air-bearing support, and advanced environmental control systems, enabling highly sensitive measurements across a wide temperature and viscosity range. It supports both steady shear and oscillatory testing modes for comprehensive material analysis.
