A Crushable Tube Filler—also widely recognized in the industrial packaging sector as a crushable glass ampoule filling machine or onion skin tube filler—is a highly specialized pharmaceutical and laboratory packaging machine designed for ultra-delicate container handling. This advanced automated equipment is engineered specifically to dose and hermetically seal fragile glass containers, commonly referred to as thin-walled, crushable glass tubes, onion skin tubes, crushable ampoules, or biological indicator tubes.
Because these specialized glass vessels are engineered with intentionally thin walls for effortless breaking during use, filling them requires an extraordinary level of mechanical precision, smooth mechanical indexing, and gentle handling to eliminate micro-fractures, glass breakage, and product loss.
Machine Engineering and cGMP Compliance
A Crushable Tube Filler (also known as a crushable glass ampoule filling machine or onion skin tube filler) is a specialized pharmaceutical and laboratory packaging machine designed to accurately dose and hermetically seal ultra-delicate, thin-walled glass containers such as crushable glass tubes, onion skin tubes, crushable ampoules, or biological indicator tubes.
These glass vessels have intentionally thin walls so they can be easily broken during use. Filling therefore demands exceptional mechanical precision, smooth indexing, and gentle handling to prevent micro-fractures, breakage, and product loss.
All product-contact parts are made from high-quality Stainless Steel 316L, while non-contact parts are made from Stainless Steel 304. The machine is built to meet cGMP standards and can integrate with laminar airflow (LAF) hoods.
The machine offers higher production output of up to 12,000 ampoules per hour, depending on the model and tube size.
It accommodates sizes from 1 ml to 10 ml with minimum change-over parts. Changeover time is short, maintenance is low, and cleaning is straightforward.
Key features include a “No Ampoule – No Filling” system, ampoule neck centering during gas flushing and filling, possibility of nitrogen gas flushing before/during/after filling, flow meters for easy flame regulation, a pre-warming station, and full accessibility for maintenance.
It is used in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries—particularly for packaging sensitive substances that require airtight, tamper-evident sealing.
It is ideal for filling liquid or chemical products into delicate tubes, especially biological indicators, chemicals, and small-dose medications that need high precision and sterility.
Yes. It allows nitrogen gas flushing before, during, and after filling, features ampoule neck centering for accurate operations, and is designed for integration with laminar airflow systems to maintain process integrity and sterility.
It delivers high precision and sterility, gentle handling that protects fragile tubes, reliable cGMP-compliant performance, flexible operation for small-scale or laboratory production, easy maintenance and cleaning, and strong batch yields with minimal product loss.
