The RH2000 series desktop capillary rheometer is a compact system that can meet most of the testing requirements encountered in capillary rheology. The series is available in single-hole or double-hole configurations in the form of RH2100 and RH2200. Rosand's two benchtop rheometers have many of the functions of the floor-standing model. The new digital drive system gives the RH2000 series unparalleled performance in terms of speed control, accuracy and dynamic working range. The latest 32-bit Windows™-based software Flowmaster™ supports this new hardware and has many new experimental possibilities.
