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.

Design conforms to ISO No. 6502 / ASTM D5289 Standards



Moving Die technology is a well-proven process that can significantly reduce your traditional testing and analysis times.

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

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.

– A rheometer is a laboratory device used to measure the way in which a liquid, suspension or slurry flows in response to applied forces
– It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer.
Rheoline Auto-Load
Fully-Automatic 16 sample loader
Supported with:
The Auto-Load comes complete with three sample trays; each tray contains 16 sample slots. Samples are placed on the tray slots, one tray at a time is inserted into the loader, and the samples are then transferred automatically to the die cavity by way of a fabric belt.
The Advantages of the Auto-Test:
– Up to 16 samples per a tray, queued ready for testing
– Laboratory personnel free to perform other tasks
– Automatic Pass/Fail of test results
Compatible Auto-Test Instruments:
– Rheoline Multi-Function Rheometer
– Rheoline Moving Die Rheometer
