viscoelastic properties determination

RHEOLASER Master has been designed to monitor the evolution of the rheological properties, such as viscoelasticity change versus aging time, or sol-gel transition with high precision thanks to the Time Cure Superposition method. MS-DWS technology provides high sensitivity to the smallest structure change with no contact and easy sample handling method.

Highlights of Rheolaser Master

Multi-sample analysis at rest

Up to 6 samples can be loaded into a disposable glass cell (4 or 20mL) and compared simultaneously. This optical technique assures no intervention or stress during the measurement and allows to study fragile and weak structures over a long period of time.

Microrheology structure analysis

> Gel point determination
> Sol - Gel transition
> Viscosity (Macroscopic Viscosity Index)
> Particle Mobility (Fluidity Index)
> Elasticity (Elasticity Index)
> Gel strength
> Ageing time
> l* (photon transport mean free path)

Wide temperature range

Temperature control up to 90°C offers various possibilities for the network analysis, structure strength, network formation time, temperature impact...

Non-intrusive technology

Measuring gel structure with optical technique assures no intervention or stress during the analysis and thus characterizing real structure properties even for weak networks like fragile gels or yogurts.

Key benefits

Rheolaser MASTER uses an optical technique with easy sample handling (4 or 20mL disposable glass cell) to analyze the samples in a non-contact and non-destructive manner.

Closed sample cells offer the possibility to measure hazardous samples (curing or volatile samples) with no risk of evaporation.

The particularity of the instrument is to measure multiple parameters in a single experiment set- up elasticity, viscosity, relaxation time information and much more.
