Pharmaceutical Ampoule Filling Machine with Integrated Washing Sterilizing Filling and Flame Sealing

This pharmaceutical ampoule filling machine merges washing, sterilizing, filling and flame sealing into one continuous GMP line, removing every manual transfer step between critical processes. It is engineered for manufacturers of sterile injectables who must demonstrate documented control over particle load and bioburden. The line can be delivered as a complete turnkey system with a laminar flow hood or isolator interface.

Regulatory inspections increasingly reject lines where sterilized ampoules are exposed to uncontrolled environments during transfer. When washing and filling are separated by conveyor belts or manual trays, the sterilized glass surface can be re-contaminated, and batch release data cannot prove the integrity of the aseptic chain. Audit findings on such lines often require expensive re-validation or line replacement.

The root cause is a broken aseptic chain: ampoules are sterilized in one room and filled in another, with human or conveyor exposure in between. Even short ambient exposure allows particle deposition on inner walls, and non-monitored transfer belts accumulate dust and lubricant residue. Without integrated sterilizing and filling, there is no continuous record linking sterilization parameters to each filled unit.

This machine closes the aseptic chain by integrating washing, tunnel sterilizing (optional dry-heat or VHP module), filling and flame sealing under one control system. Each ampoule is tracked through the line, and sterilization temperature, residence time and filling data are logged by the PLC for batch reporting. The enclosed transfer path with HEPA-filtered air curtain prevents re-contamination between sterilizing and filling stations.

• Integrated sterilizing module: optional dry-heat tunnel at 300–350°C or VHP chamber matched to your batch size
• Continuous aseptic chain: no manual transfer from sterilization to filling, eliminating re-contamination risk
• Batch data logging: PLC records sterilization temperature, residence time and filling volume per batch
• HEPA air curtain: enclosed transfer path keeps the filling zone at Class 100 (ISO 5) when paired with a hood
• Ceramic piston filling: no metal-to-liquid contact, compatible with WFI, saline and antibiotic solutions
• Flame sealing station: dual-burner design seals 1–20ml ampoules with consistent neck fusion

This line is built for sterile injectables: antibiotics, cardiovascular drugs, hormones, peptides and oncology preparations packed in glass ampoules. It is the standard choice for new GMP plants in emerging markets that must pass WHO-GMP or PIC/S audits with a documented aseptic process. The integrated configuration also reduces cleanroom floor area, because washing, sterilizing, filling and sealing share one enclosure instead of four separate rooms.

Contract manufacturers running multi-product campaigns benefit from the recipe system, which stores validated parameters for each drug and ampoule size, including sterilization time and filling speed.

Decide first whether you need dry-heat or VHP sterilization: dry-heat tunnels suit large volumes of heat-stable glass, while VHP suits smaller batches and heat-sensitive products. Second, confirm your cleanroom classification, because the machine height and hood interface differ between ISO 8 rooms and isolator installations. Third, request a media-fill validation protocol from the supplier to prove the aseptic chain meets your regulatory standard. Finally, compare total cost of ownership, including gas, power and validation documentation, not just the purchase price.

Q: Does the integrated sterilizing module replace a separate sterilizing tunnel?

Yes for most installations. The optional dry-heat tunnel module performs depyrogenation at 300–350°C with a 5–15 minute residence time, which meets USP 40/40/40 requirements. For plants that already own a tunnel, we supply the machine without the module to reduce cost.

Q: Can the line be validated for PIC/S or WHO-GMP audits?

Yes. We provide IQ/OQ documentation, FAT/SAT protocols and support for media-fill trials. The PLC logs all critical parameters, giving auditors a complete electronic batch record.

Q: What is the changeover time between different drugs?

For a standard CIP/SIP cycle with recipe reload, changeover takes 2–4 hours including cleaning validation. The quick-release filling heads and nozzle sets reduce mechanical work to about 30 minutes; the remaining time is cleaning and line clearance.

Q: What filling pumps are available for viscous or oily injections?

We offer three options: ceramic piston pumps for standard aqueous solutions, peristaltic pumps for shear-sensitive biologics, and rotary piston pumps for oily or viscous formulations. Pump heads are interchangeable on the same frame.

Every machine is test-run with water and dummy ampoules for 72 hours before packing, and a sealed calibration report is shipped with the unit. The machine is wrapped in anti-rust film and secured in an export-grade wooden case with foam inserts, suitable for sea or air freight. We supply CE, GMP and ISO 9001 documentation, a 12-month warranty on parts, and lifetime remote technical support. On-site installation, operator training and IQ/OQ/PQ validation assistance are available on request.
