Rheometer

Rheometers are high-precision instruments that measure flow and deformation by applying a force to a sample and measuring the resulting stress or strain, allowing for measurement of viscosity and modulus. Rheological measurements are typically performed using a high-precision instruments known as rheometers to obtain critical material parameters such as viscosity and modulus. With a rheometer, viscosity measurements extend far beyond the limits of a traditional viscometer, characterizing non-Newtonian behaviors like shear thinning, thixotropy, and yield stress of complex fluids (emulsions, suspensions, paints, inks, coatings, slurries). Oscillatory rheology measures viscoelasticity (Storage Modulus, Loss Modulus, Tan Delta) of materials ranging from low-viscosity fluids to stiff solids in DMA mode (Dynamic Mechanical Analysis).
