RHEOLASER Master

A precious tool to characterise viscoelasticity and its evolution

The state-of-the-art device RHEOLASER MASTER is dedicated to monitor evolution of the rheological properties, such as viscoelasticity change versus ageing time, or sol-gel transition with high accuracy thanks to the Time Cure Superposition (TCS-) method.
RHEOLASER MASTER enables the measurement of the evolution of viscosity and elasticity, in bulk samples, without any mechanical stress. The analysis takes place at rest, allowing to monitor sample evolution, such as gelation, rheology ageing, or samples stability. The measurement is performed in a closed glass cell, preventing any evaporation or drying, and making it safe to operate at all time.
