Fluidicam RHEO is an innovative optical rheometer for accurate viscosity analysis even for very liquid samples. The flow visualization in a microfluidic channel, presents multiple benefits to rheology determination: strong confinement offers high shear rate analysis, small sample volume requirements and extremely fast temperature adjustments.

Key benefits:

Fluidicam RHEO is a simple to use instrument with high repeatability and precision, small sample consumption allows multiple experiments to be carried out without the need to re-sample. 

The enclosed system provides additional benefits: volatile, fast drying samples can be easily characterized. The possibility to choose the reference solutions means that either relative or absolute viscosity can be measured.

Specially designed heating plate reduces the time required to adjust the temperature and makes possible to measure viscosity from 4 to 80°C in less than 15min.
