Rheonaut Module for HAAKE MARS Rheometer

The Thermo Scientific Rheonaut module is a new compact FTIR module for the Thermo
Scientific HAAKE MARS rheometer platform.  With the new Rheonaut module, users can
understand the cause of rheological properties on a microscopic level: Dynamic
rheometry and FTIR spectroscopy can be employed simultaneously to monitor the
molecular structure development during the reactive processing of a sample and to
detect interactions when used in parallel.

Since infrared spectroscopy is a tool capable of identifying the nature of molecular
structures and transformations, the addition of an FTIR spectrometer to a rotational
rheometer gives the researcher another level of detail pertaining to the comprehension
of rheological applications.

With a rheometer, the steady-state and time-dependent viscoelastic properties of a
material can be studied as a function of stress and/or strain. However the viscoelastic
properties of a material depend on the structure and especially the structural changes of
the material on the molecular level. Infrared spectroscopy is an excellent tool for
determining the identity and quantities of molecules in a sample.

Using the Rheonaut, both physical and chemical information can be obtained on a sample
at the same time, using one instrument. The result enables a comparison of chemical
information with rheological properties. The Rheonaut operates in the mid-infrared
spectral range since all fundamental absorption bands of a sample are typically found
between 400–4000cm-1 (2.5–25µm). This covers the so-called fingerprint region which is
generally accepted as unique for each molecule.

The Rheonaut technology features:

  • Simultaneous rheology and FTIR spectra measurements
  • A compact module for the Thermo Scientific HAAKE MARS rheometer
  • ATR (attenuated total reflection) principle
  • Analysis of structural changes under shear/deformation
  • Extensive investigation of thermal/UV curing reactions
RheoScope Module for the HAAKE MARS Rheometer

The Thermo Scientific RheoScope Module for HAAKE MARS Rheometer
offers rheological measurements with optical analysis.  

It simultaneously measures rheological properties and changes in the
microscopic structure of the tested sample.  Results allow researchers
to understand the mechanical properties of the material, and to speed
formulation development, process optimization and product
processability. The RheoScope module consists of an optical
microscope, digital video camera and temperature control unit used in
conjunction with the
Thermo Scientific HAAKE MARS Rheometer
platform.  Choose from two temperature range versions - Standard
and High Temperature for polymer melts.

Features:
  • Compact and full integration with the MARS Rheometer platform
  • All measuring modes including normal force measurement
    available with simultaneous recording of microscopic properties
  • Camera and microscope control via RheoWin software
  • Simultaneous rheological and optical measurements
  • Visualization of data and images in one software package
  • Analysis of structural changes under shear
  • Image analysis software for determining particle sizes, particle
    size distribution and structure analysis
