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 and well-plates.

Overhead gravimetric dispensing of waxes into vials while maintaining the temperature of the substance throughout the entire transfer
The Heatable cartridge for waxes (up to 90 oC up to 500 Pa.s)
- 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 the addition of wax or any other material into any formulation vessel, reactor, vial etc. on the platform deck, while mixing, 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 automatically finds 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 and Barcode Reader
The MultiGripper is a tool for transporting vials and MTPs on Chemspeed platforms. A transport may 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 …).
