Automated Powder Dispensing LibraryDoser®
LibraryDoser® is a fully automated powder
dispensing solution engineered for high-precision, gravimetric dosing of
solid compounds. Designed for true walkaway operation, it
eliminates manual weighing variability, improves throughput, and ensures
consistent, traceable results across compound libraries and R&D workflows.
By
integrating robotic handling with a high-resolution
analytical balance and closed-loop gravimetric control, LibraryDoser®
delivers reliable dosing accuracy—even for low-weight and difficult
powders—while minimizing cross-contamination and operator exposure.
