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.

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

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
