Rheosys Merlin VR Viscometer/Rheometer

The Rheosys Merlin VR is a versatile instrument that can easily generate precise data in terms of viscosity, flow curves and yield stress. It is suitable for investigating the mixing, stirring and pumping behaviour of coatings, emulsions and dispersions, as well as for performing conventional flow and viscosity profile experiments.

The device features a built-in thermoelectric temperature control system and the ability to conduct temperature isothermal and ramp experiments. It comes complete with co-axial cylinders, and cone and plate and parallel plate measuring systems, enabling the unit to routinely measure a wide range of materials under varied conditions.

The product offers continuous display of viscosity, measured temperature, temperature setpoint, shear rate, shear stress, angular velocity, torque (uNm), % torque and measuring system status on the instrument LCD display or in the Windows software. Research software ‘micra’ lets users build their own rheological tests — from quick single-point measurements to complete viscosity profiles and yield stress determinations — without the need for complicated test method set-ups.

The innovative design incorporates a thermoelectric temperature control system (-10 to +120°C) that allows isothermal, step and/or ramp temperature profiles. The DIN standard sample measuring systems of cone and plate, parallel plate, and bob and cup, coupled with a wide shear rate and torque range, provide a measurable viscosity range from 1 to 1E08 cP.
