- Suitable for research and development, formulation development, quality control, material science, chemistry, biofluids and energy-related flows involving complex rheology.
- Technical support from facility staff for test setup, sample preparation, geometry selection, temperature control and data interpretation (e.g., storage modulus, loss modulus, yield stress).
Features Working Principle
Working Principle
The rheometer works by applying a controlled deformation (strain) or load (stress) to a sample and measuring the resulting response (torque, displacement, shear rate). Wikipedia+1
- In a typical rotational rheometer (such as the MCR 52), a sample is placed between the measuring geometry (e.g., cone and plate or parallel plates). The upper geometry rotates (or oscillates) while the lower plate remains fixed. Shear is induced in the sample.
- The instrument measures the torque required to maintain rotation or oscillation and the angular velocity/strain. From this data, shear stress, shear rate and viscosity are derived. Technology Networks+1
- For viscoelastic materials, oscillatory tests measure storage modulus (G′) and loss modulus (G″) by imposing a small oscillatory shear strain and recording the stress response and phase angle between stress and strain. Technology Networks
- The instrument can thus characterise Newtonian fluids, shear‐thinning or thickening non-Newtonian fluids, yield behaviour, thixotropy, and other complex rheological phenomena. TI Instruments+1

Sample Preparation, User Instructions and Precautionary Measures
Instruction for Sample Preparation
Sample Preparation:
- Ensure the sample is homogeneous, free of air bubbles or large particles if required for the test.
- Provide sample volume as required by geometry; clean geometry surfaces, apply sample carefully, avoiding air entrapment.
- Report material type, expected behaviour (Newtonian vs non-Newtonian), temperature range, and geometry preference.
- If testing at elevated or reduced temperature, ensure the sample is pre-conditioned.
User Instructions and Precautionary Measures
- User Instructions & Precautions:
- Book a slot via the facility booking system; provide sample details and test requirements ahead of time. Centre for Sophisticated Instruments
- Trained users only; facility staff will assist with geometry selection, test protocol set-up and run.
- Clean up the sample after the test, remove residues, clean geometry surfaces, and log any irregularities.
- Ensure safe handling of materials, especially if testing high‐temperature, corrosive or particulate-loaded samples.
- Avoid running tests beyond rated shear/stress limits; monitor for instability, slip or instrument alarms.
- Dispose of samples responsibly; keep geometry clean to avoid damaging the instrument.
