The Oscillating Disc styled rheometer enjoyed renowned popularity in the early 60s and 70s. It is one of the most valued curemeters in the rubber industry to date, and still in continuous use. We understand that laboratories are reluctant to convert to the tried and proven specifications of a Moving Die Rheometer scenario, but need to gain the latest measurement technology.


Prescott Instruments have fashioned a prefect synergy of traditional principles and the latest modern technologies to build our Oscillating Disc Rheometer, more generally known as an ODR. Our design aims to revolutionise a classic and provide a seamless transition, when upgrading laboratory equipment.


The Prescott Rheoline ODR is equipped with high precision micro production die and rotor assembly. Using a microprocessor based PID control system; the temperatures of the dies are accurately maintained through the testing process. The test material sample is placed on the rotor and is secured in placed by pressure controlled platens.


The instrument is easy to maintain, and designed for ease of access. The oscillation amplitude can be mechanically adjusted with the options of 1.0 °, 3.0 ° and 5.0 °.
