Malvern Rosand RH7 and RH10

  • High force range (up to 100kN) and wide dynamic speed range (>225,000:1) allow test correlation with real material processing conditions
  • Twin bore barrels as standard enable absolute shear viscosity measurements and simultaneous calculation of extensional (elongational) viscosity
  • Range of optional barrel sizes and barrel materials to permit measurement of thermally-sensitive, chemically-aggressive or aqueous-based samples

Robust research capillary rheometers for high force conditions

Rosand capillary rheometers characterize the rheology of materials by extrusion under high pressures, shear rates and a range of temperatures, conditions which are directly relevant to processing. Applicable to materials from polymer melts to ceramics, and from foodstuffs to inks and coatings, a Rosand capillary rheometer enables optimization of process conditions and material properties for critical product functionality

About Rosand RH7 and RH10
Used in hundreds of research laboratories around the world, the robust 'H' frame design of Rosand RH7 and RH10 floor standing capillary rheometers allows operation under ultra-high loading conditions, as well as providing optimized space for multiple accessory configurations.
