Automated sample preparation system FLEX LIQUIDOSE

for the pharmaceutical industryfor forensicsreagent dispensing

Overview
FLEX LIQUIDOSE provides fully automated liquid dispensing workflows by combining gravimetric and volumetric control for liquids, (highly) viscous liquids, pastes, creams and waxes. The modular FLEX deck integrates Gravimetric Dispensing Units (GDU-HV and GDU-V) with an overhead precision balance for in-place weighing and a Multi-Channel Liquid Handling Tool (4-Needle Head) for volumetric dispensing. Supported viscosity range: ~1 mPa·s to 500,000+ mPa·s; dosing scale: milligram to multigram.

Key capabilities

• Two Gravimetric Dispensing Units (GDU-HV and GDU-V) with integrated overhead precision balance for automated dispensing and simultaneous weighing into vials, reactors, well-plates and other destinations.
• Volumetric dispensing and aspiration via a chemistry-proven Multi-Channel Liquid Handling Tool (4-Needle Head) with four independently controlled needles; interchangeable inner diameters for small volumes, suspensions or high-viscosity fluids.
• Precise gravimetric control across mg–g scales and wide viscosity range to handle liquids, viscous media, pastes, creams and waxes.

Applications and workflow elements

• Gravimetric and volumetric dispensing for formulation development, sample preparation and analytical workflows.
• Precision dosing in sample prep workflows from milligram to multigram scale.
• Handling suspensions and high-viscosity media using larger-diameter needles; small-volume handling using smaller needles.
• Compatible integrated steps: mixing, (screw) capping, labelling/barcode reading and downstream analysis.

Benefits

• Improved throughput: the balance moves between targets to enable continuous dispense-and-weigh without relocating samples to a separate balance.
• Anti-drip system reduces cross-contamination risk and enables addition of ingredients into fixed vessels while mixing, heating or cooling.
• Automatic dispensing cartridge exchange for uninterrupted operation when a source container is depleted.
