The RHEOLASER Master was designed to monitor the evolution of rheological properties, such as viscoelasticity changes in comparison with aging time or sol-gel transition against high precision that is made possible by the Time Cure Superposition method. The Rheolaser Master’s MS-DWS technology yields high sensitivity even for the smallest structural change. This mechanism is done without contact and with an easy sample handling method.

Multi-Sample Analysis at Rest
The disposable glass cells (either 4 mL or 20 mL) may load and simultaneously compare up to 6 samples. This technique avoids any intervention or stress during the measurement, allowing the study of fragile structures over longer time periods.
Wide Temperature Range
The Rheolaser Master features temperature control of up to 90 °C, offering various possibilities for network formation time and analysis, structure strength, and temperature impact.
Microrheology Structure Analysis
- Gel point determination
- Sol - Gel transition
- Viscosity (Macroscopic Viscosity Index)
- Particle Mobility (Fluidity Index)
- Elasticity (Elasticity Index)
- Gel strength
- Aging time
- l* (photon transport mean free path)
No intervention or stress is ensured whenever gel structures are analyzed. This enables users to determine real structure properties even for weak networks such as yogurts or fragile gels.

RHEOLASER Master utilized an optical technique with easy sample handling through 4 mL or 20 mL disposable glass cell in order to analyze the samples in a non-contact and non-destructive manner.
Through closed samples, the system offered the possibility of measuring hazardous samples (such as curing or volatile sampled) without any risk of evaporation.
The instrument is particularly useful in measuring multiple parameters within a single experimental set-up. The Rheolaser Master could measure elasticity, viscosity, and relaxation time information at the minimum.
