New Family of RST Touch Screen Rheometers
The new RST Series offers the quickest and most comprehensive capability for making rheological measurements, whether it ’s single point viscosity for QC or complete flow curve analysis for R &D. The RST Rheometers are unique because they operate in both controlled stress and controlled rate modes and can perform all of the following tests: viscoelastic modulus, yield stress, viscosity vs. shear rate profile, thixotropy calculation, creep behavior, recovery after flow, and temperature...
