Automated versatile gravimetric solid dispensing


Chemspeed's solution

Chemspeed’s FLEX POWDERDOSE deck modularity allows the user to execute and perform a variety of sample preparation workflows in a fully automated fashion. 

The gravimetric dispensing units (SWILE, GDU-Pfd, GDU-P models) are used to perform automated, gravimetrically controlled dispenses of a wide range of solids in the sub-milligram to multigram scale. The dispensing modules pick the appropriate container, dispense the solids and powders gravimetrically, and then place the container back to its storage position and picks the next one. All dispensing units include an overhead balance and allow dispensing and simultaneous weighing of powders into various vials, tubes, well-plates and / or reactors.

Powerful advantages

  • Decrease in cost per sample up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Ventilated hood for safety and trolley.
  • Optimized footprint (3x3 ft, 90x90 cm) versus capacity - all while reducing costs and maximizing return on investment.
  • Gravimetric solid dispensing (low density, sticky, any particle size, spherical or granulates shapes, beads and tablets) into an unlimited choice of vial / plate / reactor formats.
  • The balance moves to the destination, increasing speed and efficiency.
  • Balance resolution down to 100 μg.
  • A large dispensing range, from μg up to g.
  • Dispensed amount, 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.
  • AUTOSUITE SOFTWARE - drag & drop experimentation with easy interface to data analysis.
  • Interface to e.g. DOE, ML, AI, LIMS, ELN, ERP.
