Macofar MICRO – Designed for security and quality in powder microdosing
The Romaco Macofar MICRO 6, MICRO 9 and MICRO 18 are intermittent motion microdosing machines for dosing sterile powders at mechanical speeds of between 5,000 and 18,000 vials an hour. The powders are filled using a vacuum / pressure system. The cylindrical glass vials are then sealed with a rubber stopper.

Powder dosing with vacuum pressure
MICRO 6 / 9 / 18
- Positive vial transport
- Automatic simultaneous adjustment of dosing port volume: dosing port
- Vacuum / pressure dosing system reduces residual powder at the end of the batch to a minimum
- High speed statistical weighing system at each dosing port checks approximately 4% of the total production
- Multiple dosing into the same vial can be performed through HMI
- Dual dosing disc solution allows two different powders to be dosed into the same vial
- Stoppering station operating by pick & place system, vacuum assisted
- Balcony design

Stoppering unit
Technical Highlights
- Maximum filling speed: 5,000 (Micro 6), 9,000 (Micro 9) or 18,000 (Micro 18) vials an hour
- Quick, easy and repeatable format changes
- Automatic height adjustment of the dosing and stoppering group; no manual adjustments required
- Flushing with nitrogen before, during and after filling
- Liquid filling group to allow product validation (media fill test)
- Drying unit reduces humidity in the dosing area
- Vertical laminar flow over the dosing and stoppering stations
