Automated Sample Preparation and Viscosity Measurement


Our proprietary overhead gravimetric dispensing technology in combination with our software allows you to automatically dispense virtually any product (low to high viscosity liquids, pastes, even melted waxes) and subsequently measure its viscosity with integrated washing and drying of the spindle. Furthermore the concept allows you to measure viscosity virtually everywhere (e.g. formulation vessel, sample vials, sample tubes).

Clean, reproducible and well documented, day by day!

Autosuite Software

The intuitive and easy to use software supports the fully unattended production of screening assays from the pharmaceutical compound library.

Integration of a Viscometer in the flex visco, e.g.

  • Range: 75 - 40’000’000 mPa·s (cP).
  • Speed range: 0.1-200 rpm.

Additional features and benefits to automation:

  • Integrated software.
  • Multistep test programs (e.g. sample preparation or formulation combined with viscosity measurement).
  • 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.
