TA Instuments Moving Die Rheometer

Description

The TA Instruments MDR One is a rotorless moving die rheometer designed for the analysis of rubber curing characteristics. This instrument is engineered to perform both isothermal and non-isothermal tests on rubber compounds, operating at a constant strain and frequency. It employs a sealed biconical die configuration that complies with major international standards, including ASTM, ISO, and DIN protocols. Key operational parameters include a temperature range from ambient conditions up to 230 °C and a frequency range of 0.1 to 2.0 Hz (6 to 120 cycles per minute). Torque measurement is handled by a robust transducer with a range from 0.001 to 20 Nm. The system's design incorporates an ultra-rigid test frame to minimize compliance and ensure data accuracy, a direct drive motor, and precision temperature control with optional cooling. For laboratory efficiency, an autosampler is available to facilitate unattended operation. The instrument is controlled via the Scarabaeus software, which provides an intuitive interface for method setup, data acquisition, and analysis, and is compatible with instruments from other manufacturers. Additional practical features include pneumatic locking cylinders for consistent sample sealing and user-replaceable seals.
