Visual Inspection & Leak Testing Machine
Automatic Ampoule/Vial Inspection & Leak Testing Machine
Automatic Ampoule/Vial Inspection & Leak Testing Machine

Ideal for inspecting visible particles such as glass shards, fibers, hair, white spots, and other foreign matter in injectable ampoules. It also checks for fill level accuracy and detects leaks caused by microcracks or pinholes. Additionally, the system can be used for oral liquid vials and water-based injectable solutions in small vials (such as lyophilized vials).
