Chemspeed's solution

Chemspeed’s FLEX LIQUIDOSE deck modularity allows the user to execute and perform 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 aspirations of liquids, (highly) viscous liquids, pastes and creams in the milligram to multigram scale. Both dispensing units include an overhead precision balance, and allow dispensing and simultaneous weighing of liquids into various vials, reactors, well-plates.

Volumetric dispensing and aspiration of liquids is done with a chemistry proven Multi-Channel Liquid Handling Tool (4-Needle Head), with four independent needles. The four needles can be operated simultaneously or individually. If required the tool can be equipped with needles of different inner diameters. Larger diameter needles for the handling of suspensions or liquids with higher viscosities, smaller diameter needles for handling of small volumes.

Powerful advantages

  • 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.
  • Automatic exchange of a dispensing cartridge - if one is empty, the system automatically takes the next container.
