Automated Viscosity Measurement Expandable with Rheology and / or Automated Sample Preparation


Automated viscosity measurements combined with our proprietary overhead gravimetric dispensing solutions and our software allows you to automatically dispense virtually any product (from low to high viscosity, pastes, even melted waxes) and subsequently measure its viscosity in virtually any sample vials. 

Clean, reproducible and well documented, day by day!

  • Automated and constant z-movements of the Viscoometer (e.g. to penetrate a sample and / or to generate z-resolved viscosity data in a well defined and reproducible way).
  • Temperature controlled measurement.
  • Time coupled measurements (e.g. overnight).
  • Measurement with in-line constant delta time between virtually any action (e.g. open vial) and viscosity measurement, controlled humidity, controlled temperature, etc.).
  • Washing installation for the viscosity spindle (passive or active washing bath).
  • Viscosity control and adjustment through conditional tasks.
  • One measurement and adjustment at a time.
  • Torque / viscosity logged during all measurement time.
  • Calculation of average viscosity.
  • Data processing with mathematical models.
  • Automated analysis of user defined values for QC.
  • Import of sets of test parameters, generate template programs of parameters (speed, time of measurement, etc.).
  • Export data along with experimental data sets of choice to Excel, Chemspeed’s Workflow Management Software or virtually any other database.
  • Export data as viscosity in cP or Pa·s, temperature, speed, spindle type, time of measurement.
  • On-line display.
