The RHEOLASER Master is an instrument that uses a technique called MS-DWS ( Multi-Speckle Diffusing Wave Spectroscopy) to probe the visco-elastic properties of a liquid or gel-like sample.
What is MS-DWS?
Multi-Speckle Diffusing Wave Spectroscopy is a technique that uses a ligh source to track the change in postion of tiny particles in a liquid or gel . From this movement a displacement curve over time is polotted which in turn in used to calculate elasticity , liquid/ solid like behaviour. gel point and the viscosity index of samples. Learn More
So what makes this instrument usefull to you as potential user ?
MS-DWS is a no contact , non-destructive technique which means the rheology of the sample is measured at rest with no artifical forces applied .
What makes this technique usefull ?
Well for fragile samples it means we can measure the change in the viscosity or visco-elastice properties ( liquid / solid behaviour) without changing the sample by applying an additional stress to it.
