Rheo-Microscopy for MCR 702 TwinDrive
Rheo-microscopy is an established technology for visualizing the inner structures of samples while applying shear and deformation forces. MCR 702 TwinDrive with the rheo-microscopy setup is the first commercial rheometer system to perform measurements in counter-rotation mode, producing a stagnation plane where the sheared structure remains at a fixed position. This stagnation plane constantly keeps the focused structure in the microscope’s field of view while accurate rheological data is obtained.Get in touch Document Finder
MCR 702 TwinDrive is equipped with a microscope holder mounted onto a board for fixing the optical system. This is the same setup used for single-drive rheo-microscopy, which means that polarized, non-polarized and fluorescence microscopy is also available in the TwinDrive setup. The holder is movable in the x- and z-direction for sample scanning in radial direction and focusing. Beside the possibility of sample focusing through the lower plate via a mirror, the system can also be positioned to focus into the sample gap from the side. The sample is illuminated by a light guide, either along the optical axis or over a suitable light guide holder.
- First commercial setup allowing to perform microscopy at the stagnation plane using the counter-rotation mode of the MCR 702 TwinDrive
- Precise rheological data in combination with microscopy: Sample is kept in focus due to produced stagnation plane
- Two types of access: from the bottom and the side, for observation of structures in different planes
- Microscopy tube from single motor setup is used and adapted
- Speed balance allows to trap and fix the structures
- Flexible choice of measuring systems: at least one lower glass required for bottom view.
- Glass-thickness-corrected lens with 20 times magnification is required.
- Options for polarized, non-polarized and fluorescence microscopy available
- Illumination along the tube or via separate fixture outside
