Powerful Floor Standing Capillary Rheometers for Research and Product Development Flexible measurement capabilities for materials under high pressure and high shear rate extrusion Since its launch, the Rosand RH7 and RH10 have set new standards in research level capillary rheometry. Today, the Rosand is used in hundreds of research laboratories around the world for a range of applications including polymers, foods, coatings and ceramics. Continuous development of the original design and its operating software has produced a generation of floor standing capillary units with market leading...

Advanced Benchtop Capillary Rheometers for Research, Product Development and Quality Control Wide range of shear rates for correlation with real material processing conditions, in one compact system The Rosand RH2000 series of benchtop 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. The RH2000 incorporates many of the features and attributes found in the floor standing models (Rosand RH7/RH10). A digital drive system gives the RH2000 series unsurpassed...

Capillary Rheometer HOW THE SYSTEM WORKS Capillary Rheometer Base Unit The Rosand high pressure capillary rheometer systems enable controlled extrusion (by volumetric flow) of a sample through a high precision die of known dimensions. This enables characterization of material flow properties, typically under conditions of high force (or pressure) and/or high shear rate. Using the twin bore barrel option and a zero length die configuration allows, simultaneous determination of shear viscosity and extensional (elongational) viscosity as a function of shear (or deformation) rate can be...

Features of Rosand Rheometers Rosand Twin Bore Principle Bi-Modal Speed Control Rosand capillary rheometers were the first to introduce the twin bore measurement principle to the commercial market. Simultaneous measurements can be made on both long and short dies to determine the inlet pressure drop at the die and, therefore, absolute viscosity, using the Bagley method. More commonly, Rosand zero length dies are used to directly measure the inlet pressure drop and measure the extensional viscosity using the Cogswell method. Bi-modal digital speed control technology has been developed for...

Rigid H Frame Design The H frame design principle provides a vertical stiffness well in excess of that achievable with cantilever or C frame designs. The frame is effectively rigid at loads well in excess of the 100 kN measurement limit. This is an important consideration in transient tests such as pVT, which rely upon compliance free measurement for accurate volume determination. Integral Fume Chamber with Extraction For operator safety, the RH7 and RH10 are equipped with a safety interlocked fume chamber with fan extraction of the gases to a vent at the back of the rheometer unit. An...

Configuration Options The Rosand capillary rheometers can be configured with a variety of options to provide complete measurement solutions across all applications. High Force Extends the maximum force (summed over both barrels if applicable) to 20 kN for the RH2000. The RH7 and RH10 have forces of 50 and 100 kN, respectively. High Speed An option for the RH2000. It extends the upper speed limit of the unit to 1200 mm/min for high shear rate measurement with no loss in speed sensitivity or available force. The high speed option is fully compatible with the high force option. An advanced,...
