Automated Dispensing, Blending, and Microwave Assisted Baking of Powders Within Highly Regulated Environments (e.g. GMP, GLP)


Robustness and ease-of-use by design

Overhead gravimetric solid dispensing / dosing and our user-friendly software, allow you to automatically dispense virtually any powder and solid into any type of destination (vials, tubes,plates, reactors, ...) without moving the destination.

Key advantages
  • Decrease in cost per sample up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Gravimetric solid dispensing (low density, sticky, any particle size, spherical or granulates shapes, beads and tablets) into the rack / reactor format of your choice.
  • The balance moves to the destination, increasing speed and efficiency.
  • Balance resolution of 0.1 mg, or 0.01 mg.
  • A large dispensing range, from a few mg up to several grams.
  • Powder dispensing / dosing robotic tool can be combined with other tools to accommodate multiple workflows.
  • Dispensed amount, mixing speed, temperature, 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 SWING MEDTECH deck modularity allows the user to execute and perform a variety of solid dispensing and blending workflows in a fully automated fashion.
The Gravimetric Dispensing Units (GDU-P, GDU-HV, GDU-V models) are used to perform automated, gravimetrically controlled dispenses of a wide range of ingredients in the milligram to multigram scale.
The modules pick the appropriate container, dispense the ingredients, and then place the container back to its station before picking the next one. All dispensing units include an overhead balance with a resolution of down to 0.1 mg, and allow dispensing and simultaneous weighing of ingredients into various vials, reactors, well-plates.

  • Exemplary dispensing time: 1g in 20 sec (depending on powder flow properties).
  • Powder dispensing capacity: (expandable with additional powder storage module)
