RH2000 Capillary Rheometer

The RH2000 Series - RH2100 & RH2200

Advanced bench-top, capillary rheometers suitable for research, product development and quality control.

The RH2000 series of bench top capillary rheometers are compact systems capable of most testing requirements encountered in capillary rheometry. The series is available in both single bore or twin bore configurations in the form of the RH2100 and the RH2200. Both versions of Rosand's bench top rheometer incorporate many of the features and attributes found in the floor standing models. A new digital drive system, gives the RH2000 series unsurpassed performance in terms of speed control, accuracy, and dynamic operating range. This new hardware is supported by the latest generation of 32 bit Windows™ based software, Flowmaster™, with many new experimental possibilities.
