Viscous dispensing / dosing technology combined with our overhead gravimetric (patented) capability and our user-friendly software, allow you to automatically dispense virtually any type of viscous liquids, pastes and creams into any type of destination (vials, tubes, plates, reactors, …) without moving the destination.
Gravimetric viscous liquids, pastes and creams dispensing and aspiration (oils, highly-viscous oils, pastes, waxes, etc.) 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 100 µg or 10 µg.
A large dispensing range, from a few mg up to several grams.
Viscous 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.
“Enabling companies like Unilever to develop new materials and improve products is exactly what the Centre was set up to achieve. I’m delighted that our strong relationships with Unilever and Chemspeed are enabling real innovation in materials discovery.”
Chemspeed’s SWING VISCODOSE deck modularity allows the user to execute and perform a variety of viscous liquid dispensing workflows in a fully automated fashion.
The Gravimetric Dispensing Units (GDU-HV and GDU-V models) are used to perform automated, gravimetically and volumetrically controlled dispenses and aspiration of (highly) viscous liquids, pastes and creams in the milligram to multigram scale. The modules pick the appropriate container, dispense the (highly) viscous liquid, and then place the container back to its station before picking the next one. Both dispensing units include an overhead balance, and allow dispensing and simultaneous weighing of (highly) viscous liquids into various vials, reactors, well-plates.
Dispensing Range and Viscosity Range without Heating
Viscosity Range with Heating
Dispensing Container Volume
Highly Viscous Liquids
down to 10 µg, optionally down to 0.01 mg with second on-deck balance
> 100 µg to 100 mg 1 mPa.s to 500’000 mPa.s
Up to waxes or substances with melt-viscosity of
Low to Medium Viscous Liquids
100 µg to 100 g 1 mPa.s to 15 mPa.s
Disposable positive displacement syringes from 100 μl to 12.5 ml
The Gravimetric Dispensing Unit for highly viscous liquids and molten waxes
The Gravimetric and Volumetric Dispensing Unit including Online Density Measurement on the fly for viscous liquids
Exemplary dispensing time: 1g in 20 sec (depending on (highly) viscous liquids properties).
SWING: up to 65 cartridges for the GDU-HV, up to 180 syringes for the GDU-V
SWING XL: up to 125 cartridges for the GDU-HV model, 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 addition of (highly) viscous liquids or any other material into any formulation vessel, reactor, vial etc. on the platform deck while mixing, heating, cooling etc.
One dispensing design and one AutoTeaching tool to cover all your (highly) viscous liquids, pastes and creams. 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.
