RheOptiCAD
A Thermo-Mechanical Rheo-Optical Device
Developed in collaboration between AgroParisTech, INRA and CAD Instruments,
RheOptiCAD® is high standard device for imaging complex systems, from
liquids to solids, under thermo-mechanical treatments.
Uniaxial shear is performed by translation of two parallel plates and temperature is
controlled using a Peltier module coupled to a water cooling system.
RheOptiCAD® is adaptable to all optical or confocal inverted microscopes, and
presents a simple, fast and reproducible way of sampling,
not depending on commercial microscopy glasses.
Features and Benefits
- Large gap range for an easy and adaptable sampling
- Perfect planarity and parallelism of shearing plates
- Suction system for microscopy glasses hold
- Observation based on ZVP principle
- Motion: linear, strain jump or oscillation
- Electric torque measurement for force estimation
- Controlled heating and cooling rate with Peltier system
- Computer controlled through Ethernet plug
- Data recording
- Designed for commercial microscopy glass
- Thermo-mechanical characteristics similar to rheological devices
