Rheometer for the characterization of pastes and inks

The Kinexus pro Active rheometer is a very precise rotational rheometer with air-bearing, which enables rotation and oscillation experiments. It is made for the rheological characterization of dispersions and soft solids and provides data for rheological standard tests such as recording flow curves, disturbance test, hysteresis, amplitude and frequency tests.

Furthermore customized instruction programming of processes regarding sections default of shear stressing enables the adjustment of operation instructions for a variety of applications (e.g. printing, processing of paint and varnish, cosmetics or food).
