Onion Skin Ampoule Filling Machine is a specialized piece of equipment designed for filling and sealing thin-walled, crushable glass ampoules, often referred to as “onion skin” ampoules due to their delicate, thin glass structure (typically 0.3mm to 0.8mm thick). These machines are widely used in pharmaceutical, biotech, cosmetic, veterinary, and chemical industries for precise filling and sealing of small-volume liquid products, such as medicines, serums, vaccines, agro-insecticides, and biological indicators. Below is a detailed description of the machine’s features, operation, and specifications based on available information:
The sterilized ampoule tray directly loaded in to slant hopper of the unit. The Synchronized star wheel delivers ampoules, one by one on moving eccentric ampoule rack in single/double/four/six/eight. During the movement of ampoule machine perform below mentioned operations:
At the end duly filled and sealed ampoules get collected automatically onto collection tray of the machine. Ampoules now can be collected for further inspection and/or sticker labeling operations.

An Onion Skin Ampoule Filling Machine is a specialized automatic monobloc system designed for filling and flame sealing thin-walled, delicate “onion skin” glass ampoules (glass thickness 0.3mm to 0.8mm). These crushable ampoules are commonly used for small-volume sterile liquids such as injectables, vaccines, serums, biological indicators, and agro-insecticides. The machine integrates nitrogen flushing, precise volumetric filling, pre-warming, and sealing while handling the fragility of thin glass with minimal breakage.
We offer four standard models:
Higher custom models can reach up to 36,000 ampoules per hour. It supports ampoule sizes from 1ml to 30ml (model dependent), with filling range 0.5ml to 25ml (or smaller volumes down to 0.1ml in special configurations) and filling accuracy of ±1%.
The machine uses the slant traveling principle along with neck centering and ampoule rotation to gently handle fragile onion skin ampoules and reduce breakage. Key adaptations include:
Sterilized ampoules move through synchronized star wheels for pre-gassing, filling with piston pumps, post-gassing, pre-heating, and LPG + Oxygen flame sealing. A “No Ampoule – No Filling” system prevents wastage.
Key features include:
These features ensure high sterility, low glass breakage, and consistent sealing quality.
