The Merlin VR
An advanced rotational viscometer / rheometer
The Rheosys Merlin VR is our most advanced and versatile instrument. The Merlin VR can easily generate precise data in terms of viscosity, flow curves, and yield stress.
The built in Peltier thermoelectric sample temperature control system gives the Merlin VR the ability to conduct isothermal and ramp temperature experiments.
The included DIN / ISO Co-Axial Cylinders, Cone and Plate & Parallel Plate measuring systems enables the Merlin VR to accurately and routinely measure a wide range of materials under varied conditions.
