Micro rheology instrument

The Formulaction Rheolaser is a micro rheology instrument that can be used to measure the rheological properties of materials under zero shear as it measures those properties without any additional applied energy.

The Rheolaser measures the mean square displacement (MSD) of particles using light scattering, specifically diffuse wave spectroscopy. From the MSD, QC level or research level, parameters can be extracted.

Simple elasticity and viscosity factors may be suitable for a QC environment. G' and G'' may also be extracted at a single frequency for base level research. For the high-level researcher, G' and G'' are available across the full range of frequencies. In addition, elasticity, relaxation time and macroscopic viscosity can be calculated. Data on stability can also be extracted.

All of these parameters are available at the click of a single button.

All frequencies are acquired concurrently.

No longer is it necessary to denature or destroy a sample to measure its rheological properties; no added force is required, so this opens up the whole new world of rheological kinetics or aging studies on a single sample.

The instrument is easy to use, there are no mechanical components where sample has to be carefully loaded - the sample simply sits in a sample tube and its Brownian motion observed.

The instrument also has six sample positions, so it is capable of multiple analyses, or some positions can be used for sample conditioning.
