Rheology MARS iQ Air

Thermo Scientific MARS iQ Air

Rheometers apply torque to twist a material (rotation or oscillation) and measures its response; from such experiments, the viscosity (visco-) and stiffness (elastic) of the sample can be calculated. These viscoelastic properties can be related to temperature, time, or frequency. Rheology is able to provide information such as viscosity, storage/loss moduli, flow behavior, elasticity and recovery of a material.

Description

Thermo
→ Temperature range: -5ºC to 200ºC (not to be used for melt rheology)
→ Geometries available:
          ⇒ Parallel plate (20mm dia, 35mm dia, 60mm dia)
          ⇒ Cone 2º (35mm dia, 60mm dia)
          ⇒ Cone 4º (35 mm dia, 60mm dia)

Uses / Applications

The rheometer allows the rheology of polymer solutions to be understood. This can be used to relate the viscosity of a polymer to its molecular weight.
This can be applied to understanding polymer suspensions, such as commonly used in shampoos, conditioners etc.
