Thermo Fisher Scientific Introduces New Optical RheoScope Module for HAAKE MARS Rheometer Platform



Visualize and Enhance the Understanding of Mechanical Properties

Karlsruhe (November 17, 2006) - Thermo Fisher Scientific, the world leader in serving
science, today introduced a new optical module for its Thermo Scientific rheometer platform HAAKE MARS. The RheoScope module simultaneously records rheological properties and changes in the microscopic structure of the tested sample. By combining rheological measurements with optical analysis, microstructures can be analyzed visually to obtain more information about a sample's mechanical properties. Combined methods are ideally suited for the analysis of shear thinning, dilatancy, thixotropy, aging and emulsification. This information is invaluable to researchers to further formulation development, process optimization and processability for food, cosmetics, pharmaceuticals, petrochemicals and other applications.

The compact RheoScope module is a unique combination of an optical microscope,
progressive-scan CCD digital video camera and temperature control unit that can be
integrated easily into the MARS rheometer platform. The Thermo Scientific rheometer can
perform normal force measurements and operate in a variety of modes, e.g. CR- or CS mode in rotation and oscillation while recording microscopic properties of the sample.
HAAKE RheoWin software controls not only the rheometer, but also the optical unit, i.e. the focus and position of the polarizator. Depending on the user configuration, 5, 10, 20 or 50x magnification is available. Data, video sequences and images can be viewed on-line as well as stored in various formats for later evaluation and analysis. Based on the RheoScope design, customized user configurations can be quickly adapted in the standard module.

Key features of the RheoScope module:
o Fully integrated into the Thermo Scientific rheometer platform
o Visualization of data and images via one software package
o Simultaneous rheological and optical measurements
o All measuring modes available including normal force
o Analysis of structural changes under shear
o Quantitative characterization of particle dynamics
o Customized user configurations available
