Rhometer

Process monitoring made easier. Weight fraction at the touch of a button.

Rhometer

Characterization of concentrated, viscous, turbid, sedimenting and colored samples no sample preparation required

  • Results within a second
  • Small sample volume requirements ( 10 ml )
  • Integrated microcontroller ( No PC cards needed )
  • Direct feed of the results into Field ESA and PA Fast Sizer 100
  • Robust design and high chemical resistivity.
  • Batch or online applicability in both lab and plant environment

Operational Principle

  • Rhometer uses oscillating glass tube technology
  • It measures the vibration frequency difference between pure solvent and dispersion to determine the density
  • Inputting the particle density allows measurements of the particle fraction

Application

  • Highly efficient product development through work at production concentration
  • Improvement in recipe stability
  • On- and off-line quality analysis and quality control
  • Rhometer is designed for production control, QA/QC and R&D tasks in:
Ceramics Food Colloids Filtration/de-watering
Paints and inks Cement Wet milling / grinding
Coal slurries Mineral processing Control of surface coating
Semiconductors Clay minerals Control of homogenization
Pigments Paper coatings Abrasives and Polishing
Light phosphors Catalysts and zeolites Nano-Dispersions
