Automated Gravimetric Highly Viscous Liquid and Wax Dispensing


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 highly viscous liquids and waxes 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 WAXDOSE deck modularity allows the user to execute and perform a variety of highly viscous liquid and wax dispensing workflows in a fully automated fashion.

The Gravimetric Dispensing Unit (GDU-HV model) with heating option is used to perform automated, gravimetically controlled dispenses and aspiration of molten wax in the milligram to multigram scale.

The module picks the appropriate heated container, dispenses the wax, and then places the container back to its station before picking the next one. The dispensing unit includes an overhead balance, and allows dispensing and simultaneous weighing of wax into various vials, reactors, well-plates.

SWING dimensions: 
1’480 x 910 x 1’860 mm 
(4’ 4 3/8” x 3’ x 6’ 1 1/4”) 

SWING XL dimensions:
2’350 x 950 x 1’920 mm 
(7’ 70” x 3’ 2” x 6’ 4”)

  • Exemplary dispensing time: 1g in 20 sec (depending on wax properties).
  • Wax dispensing capacity: (expandable with additional wax storage module) 
    SWING: up to 65 cartridges for the GDU-HV
    SWING XL: up to 125 cartridges for the GDU-HV
  • 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 addition of wax or any other material into any formulation vessel, reactor, vial etc on the platform deck whilemixing, heating, cooling, etc.
  • The GDU-HV heated cartridge inserts are disposable. The plunger and the actual heated jacket are non disposable and can be reused.
  • One dispensing design and one AutoTeaching tool to cover all your heated and waxes materials. The sophisticated algorithm of the software finds automatically the best conditions to dispense your ingredient.
  • Automatic exchange of a dispensing cartridge if one is empty, the system automatically takes the next container.
  • The MultiGripper is a tool for transporting vials and MTPs on Chemspeed platforms. A transport can be intended for one of the following reasons:
    Weight determination on the balance rack
    Barcode reading
    Transportation to a rack with additional functionality (heating, agitation ...) 

Optional: integrated Barcode Reader. The Barcode Reader automatically identifies 1D and 2D barcodes on vials and MTPs.

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).

Complete Software Solution: Design, Execute, Analyze, Report

Chemspeed’s AutoSuite User Interface & Executor software packages execute and control all modules of the entire product development cycle. They control all Chemspeed robotic platforms and any other integrated 3rd party software and hardware.

AutoSuite is a software with a user friendly interface  which allows easy workflow orienteted programming. Many features such as gravimetric dispensing are automatically calibrated, eliminating tedious optimization steps.

  • The AutoTeaching tool simplifies dispensing applications without manual trials and is applicable to e.g. solids eliminating the need for manual optimization before the dispenses are done.
  • Easy programming: drag-and-drop workflow steps or just execute standard workflow protocols.
  • Barcode tracking.
  • ARKSUITE Workflow Studio and Internet of the Lab Tools (e.g. DoE, data mgt, substance parameter database, inventory mgt, product mgt, run mgt). It includes a full document management system (electronic labjournal) and is 21 CFR Part 11 compliant. The software scales from a single PC to large network installations with multiple hardware and clients.
