Reologica StressTech HR
research spec. high resolution controlled
stress rotational rheometers, & Reologica
Viscotech controlled stress
rotational rheometers to perform a variety of rheological tests, ranging
from constant rate viscometry
to oscillation strain control as
functions of deformation rate,
time or temperature.

These rheometers provide a highly sensitive and accurate method of determining
discrete changes in properties such as molecular
weight & molecular weight
distribution caused through thermal
/ physical / Chemical
degradation. The instruments have extensive temperature
ranges and can be run isothermally or thermally ramped, (StressTech HR:
-15°C to 400°C and ViscoTech: -10°C to 100°C). For this
reason these machines are an intrinsic part of our quality
control & failure analysis
services.
The rheometers are equipped with a wide selection of modular cone & plate, plate-plate & coaxial cylinder measurement systems providing the flexiblity to characterise materials ranging from highly filled / high molecular weight polymers to low viscosity solutions / oils & pastes / weakly structured materials. A disposable plate-plate measurement system is also available to use in conjunction with the rheometers. The disposable plate system is ideally suited to the characterisation of key parameters such as melt stability determination, thermal degradation studies, measurement of cure kinetics & Reactive Viscosity data for use in Moldflow & Moldex3D, and the characterisation of polymer solutions containing aggressive chemicals or solvents.
Up until the acquisition of Reologica AB by Malvern Instruments Ltd in early 2010, Gammadot Rheology was the UK location for demonstration of Reologica AB's quality rotational rheometer range.
