Rapid Visco Analyzer RVA 4500

The RVA measures the viscosity and performance of starches, raw materials, ingredients and foods using controlled temperature and shear. It can be used to characterize ingredients, intermediates and finished products to optimize quality and performance.


Features and Benefits

  • High Sensitivity: Direct drive motor and control system for low viscosity samples.
  • Wide Viscosity Range: Optimized measurement system for high viscosity samples.
  • Rapid Viscosity Profile: Standard starch pasting test in 13 minutes.
  • Robust: Suitable for factory floor to analytical laboratory.
  • Traceable: Calibration check with traceable standards to satisfy ISO9000/ISO17025 and other Quality System requirements.
  • Glass-free: Safe for food manufacturing areas.
  • Precise: Accurate, crystal-locked stirring speeds, heating and cooling rates, ensures repeatable results between RVAs.
  • Standard: Standard methods approved by ICC, AACC International and others.
  • Relevant: Tailor test routines to emulate processing conditions in industry.
  • ER/ES Compliant: Electronic Records/Electronic Signatures compliant TCW3 can create traceable, secure results and reports.
