LOCUS ROBOTICS engineers gravity-based filling systems for low-viscosity liquids, offering unmatched simplicity and maintenance-free operation.
✔ Modular Design: 2–16 filling heads (expandable)
✔ Precision Conveyor Sync:
Pneumatic stoppers position containers
Nozzles lower/raise automatically (±0.5mm repeatability)
✔ Throughput: Up to 120 BPM (16-head systems)
Multi-Roller Heads:
6-8 Rollers: For micro-dosing (0.1–10mL, ±0.5%)
3 Rollers: For high-flow (50–5000mL, ±1%)
Quick-Change Tubing: Swap in <30 sec (tool-free)
