Rheoline MDR

Prescott’s Rheoline Moving Die Rheometer (MDR) has been designed to carry out, tried and proven test specifications in accordance with international standards. Providing fast, accurate data and meeting the requirements of a modern testing laboratory, the Rheoline MDR is ideally suited to both the production environment and for use in the development of elastomeric compounds.

Moving Die technology is a well-proven process that can significantly reduce your traditional testing and analysis times. At the heart of the Rheoline system is a rotor-less biconical die assembly with an internal cavity of 4.5 cm3. The lower die oscillates at 1.67 Hz over amplitudes of 0.5 °, 1.0 ° and 3.0 ° whilst the top die remains fixed and accurately measures the reaction torque, producing precise, repeatable data in an extensive range of testing environments.

The digital electronics module and 16-bit PID algorithm apply quick, accurate temperature control with a variation of ± 0.03 °.


Prescott Instruments have developed its own unique patented technology; an automated belt system designed to convey rubber samples into a test chamber, ensuring that the material under test remains in contact with the dies and reduces slippage.

In addition, programmable temperature zones and/or a pressure module is also available as an optional extra. Contact us for more details.
