Freeze-Dried Powder (Lyophilized Powder)
We offer automatic visual inspection & leak testing equipment for freeze-dried (lyophilized) powder formulations in vials

We provide integrated automatic visual inspection and leak testing solutions for lyophilized (freeze-dried) powder products in vials (2–30 ml), suitable for both molded and tubular vial formats. These visual inspection systems are designed to detect surface contaminants, cosmetic defects, fill volume discrepancies, and container closure integrity issues at inspection speeds of up to 400 vials per minute. Lyophilized powders are widely used in pharmaceutical and cosmetic applications for their ability to preserve the stability and efficacy of active ingredients. Our medical inspection systems are tailored to ensure these products meet stringent quality and safety requirements.

Liquid Dosage
Key Features for Freeze-Dried Powder Applications
  • Combines computer vision with laser spectroscopy in a fully servo-driven, multi-station system for high-speed, high-accuracy performance
  • Equipped with high-resolution industrial cameras, offering inspection accuracy beyond manual visual checks where the detection parameters can be adjusted or fine-tuned based on specific product requirements
  • Compact, servo-driven machine design ensures smooth handling and minimizes the risk of vial breakage during transport
  • Tooling features a dowel-pin design and adjustable platforms for fast and efficient changeovers between vial sizes offering flexible configurations
  • Supports 3–4 levels of user access with customizable permissions where all operations, parameter changes, and production data are traceable to ensure GMP compliance
