Semi-automatic powder dosing system
Achieve precise micro-dosing for pharmaceutical powders with a flexible system ideal for small batches, ensuring accuracy and compliance with pharmaceutical development standards.

Precisely Doses and Fills Powders
The Drum Lab from Harro Höfliger is a versatile semi-automatic table-top unit designed specifically for precision micro-dosing of powders starting from 0.5 mg. It is tailored for pharmaceutical manufacturers, medical device companies, and laboratory research facilities engaged in developing and producing small batches of pharmaceutical and diagnostic products. At its core, the Drum Lab uses a drum filler to ensure precise and reproducible dosing into various primary packaging, including capsules, vials, cartridges, syringes, and blisters. It is equipped with an integrated checkweighing system that maintains compliance with 21 CFR Part 11, crucial for regulatory environments in pharmaceutical applications. Designed for flexibility, it utilizes a removable puck transport system that facilitates easy handling and adaptation to customer-specific requirements. Offering a throughput of up to 400 parts per hour, the system’s compact design (approximately 800 x 840 x 675 mm) makes it ideal for laboratory and pilot-scale operations. With a 10-inch touch panel and integrated control cabinet, the Drum Lab streamlines operations and enhances productivity in R&D settings.
