Automated Gravimetric Solid, Powder, Liquid, Viscous Liquid, Wax Dispensing / Dosing - Precision, Accuracy, Speed, Traceability (incl. applications in GMP environments)


Dispensing / dosing technology combined with our overhead gravimetric (patented) capability and our user-friendly software, allow you to automatically & gravimetrically dispense virtually any type of compound into any type of destination (vials, tubes, plates, reactors, ...) without moving the destination and while sample processing (e.g. heating / cooling, mixing).

Robustness and ease-of-use by design

Key Advantages

  • Decrease in cost per sample up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Gravimetric viscous heated materials and molten waxes dispensing and aspiration into the rack / reactor format of your choice.
  • 4-Needle Head for volumetric liquid handling and sampling.
  • 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.
  • 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.

Breakthrough dispensing technology: overhead gravimetric dispensing while mixing, heating, refluxing and / or cooling
Technical Details

Chemspeed’s SWING XDOSE deck modularity allows the user to execute and perform a variety of compound / substance handling workflows in a fully automated fashion.

The Gravimetric Dispensing Units (SWILE, 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 ingredient properties).
  • Dispensing robotic tool capacity: (extandable with additional ingredient storage module) SWING: up to 32 cartridges for the GDU-P


  • Up to 32 cartridges for the GDU-P
  • Up to 65 cartridges for the GDU-HV
  • Up to 180 syringes for the GDU-V


  • Up to 56 cartridges for the GDU-P
  • Up to 125 cartridges for the GDU-HV
  • Up to 360 syringes for the GDU-V
  • Reduced dispensing time: the balance moves from one target to the next, continuously dispensing and weighing without having to move the target to the balance. The anti-drip system avoids cross contamination and enables to add any ingredient into any (fixed) formulation vessel, reactor, vial etc. wherever on the platform deck while mixing, heating, cooling etc.
  • AutoTeaching tool to cover all your ingredients. The A.I. algorithm of the software finds automatically the best conditions to dispense your ingredient.
  • Automatic exchange of a dispensing cartridge if one is empty or clogged (container spanning).

4 dimensions of modularity and flexibility

  • Individual platform configuration tailored to your workflow with market-proven offthe-shelf components.
  • Robotic platforms which can be easily integrated into other systems to enable multi-workflow processes (e.g. Formulation, Application and Testing procedures all integrated in a single platform).
