Transform Soft Material Testing with Rheodialysis for NETZSCH Kinexus Rheometer
Rheodialysis technology: A new tool for real-time characterization and testing of soft materials.
Rheodialysis allows for real time changes of a sample´s chemistry by applying ions via a membrane into the sample on a rotational rheometer.
Explore the innovative rheodialysis developed by the University of Liverpool (Dr. Anders Aufderhorst-Roberts, Lecturer in Sustainable & Biological Materials at the School of Engineering) and Durham University (Prof. John Girkin, Professor of Biophysics at the Department of Physics) in collaboration with NETZSCH, offering an unprecedented capability to probe the interplay between chemical environments and mechanical forces in soft materials.

“More often than not, when a material encounters a change in shear environment, this coincides directly with change in chemical environment. But commercial rheometers cannot control shear and chemistry simultaneously and this represents an obvious blindspot when understanding the processing of soft structured materials and their end use applications. It’s also integral to many biological processes.
Rheodialysis is a new device that represents our shared vision to address this blindspot. It’s a joint endeavour between my team, our collaborators at Durham University and our colleagues at NETZSCH. Rather than commercialising this device, we’re making it fully and freely available to all interested users. If you believe this might help you answer new research questions, we’d like to hear from you. Please get in touch below.”
Why Choose Rheodialysis for NETZSCH Kinexus?
Almost all soft materials ‒ biological or industrial ‒ are highly sensitive to mechanical StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress and their chemical surroundings. This rheology system uniquely enables you to:
- Simultaneously control chemical environment and mechanical forces in your shear rheometer tests
- Monitor real-time changes in rheological properties, including viscosity and shear StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress during dynamic chemical changes
- Understand synergy between chemical and mechanical stimuli for soft solids, gels, and dispersions
- Model realistic processes such as digestion, drug release, and blood clotting kinetics with automated chemical diffusion control
