MULTIPLANT / AUTOPLANT PRECIP: (Mixed) Oxides by pH-Controlled Precipitation, Ion Exchange and Sol-Gel Process

The leading technology in overhead gravimetric dispensing / dosing (patented) combined with our reactor and process excellence, and our user-friendly software, allow you to standardize and accelerate your (mixed) oxide synthesis workflows (precipitation, sol-gel, ion exchange).

Example Customer testimonial

Using Chemspeed’s AUTOPLANT we have been able to test a lot of ideas for making new aluminas in a small amount of time.

Key Advantages:

  • Decrease in cost per experiment up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Up to 36 experiments per run on an autoplant, up to 6 experiments per run on a multiplant.
  • Independent control of all process parameters in each reactor with PAT like PSD, pH.
  • Independent and precise temperature and stirring control in each reactor.
  • Up to 8 independent liquid feeds per reactor.
  • pH measurement and control (e.g. swingin pH control via acid and base).
  • Vessel-to-vessel transfer for multistep processes.
  • Gravimetric solid and viscous liquid dispensing.
  • 4-Needle Head for volumetric liquid handling and sampling.
  • Feeding and sampling under reaction conditions.
  • Cleaning in place (e.g. automated cleaning, inserts).
  • Dispensed amount, stirrer speed, temperature, pressure, time…, and other data are stored in a read only log file.
  • Easy access to data with a convenient interface to pull results into Excel or virtually any other software.
  • Interface to DOE..

Technical Details

Chemspeed’s MULTIPLANT/ AUTOPLANT PRECIP deck modularity allows the user to execute and perform a variety of workflows in a fully or semi-automated fashion.

New or better, high-quality (mixed) oxides require accurate control of manyre action parameters, therefore automated workflow solutions are key to accelerate their development.
