Automatic Two Head Closed Ampoule Filling & Sealing Machine
Advanced Aseptic Liquid Packaging for Pre-Sealed Glass Ampoules
In sterile pharmaceutical manufacturing, clinical trials, and high-end cosmetic packaging, maintaining fluid purity and container integrity is non-negotiable. The Automatic Two-Head Closed Ampoule Filling & Sealing Machine from Harsiddh Unimach Pvt. Ltd. is engineered specifically to meet the rigorous demands of processing closed-form (D-type) glass ampoules. By combining opening, gas purging, high-precision volumetric dosing, and hermetic sealing into a single, compact automated footprint, this system eliminates environmental exposure risks and delivers reliable, contaminant-free results.
Operating at the intersection of high mechanical synchronization and precise thermal control, this two-head machinery solution is ideal for medium-scale production plants, research laboratories, and contract manufacturing facilities. Designed in strict compliance with current Good Manufacturing Practices (cGMP) and global safety standards, it ensures total processing control for your high-value injectable formulations.
The Closed Ampoule Advantage: Maximizing Aseptic Security
Traditional open ampoules risk exposure to airborne micro-particulates, glass fragments, and microbial contamination during transport and storage before they ever reach the filling line. Closed ampoules (pre-sealed by the glass manufacturer) solve this issue entirely.
The advanced engineering from Harsiddh Unimach Pvt. Ltd. capitalizes on this safety profile by keeping the container hermetically closed until the precise millisecond it enters the sterile filling zone. The machine opens, flushes, fills, and re-seals the glass in a continuous, uninterrupted sequence. This rapid cycle leaves zero opportunity for atmospheric contamination, making it the preferred choice for biological injectables, unstable chemical reagents, and premium skin-care serums.
Step-by-Step Operational Processing Flow
Mechanical precision and synchronized timing drive the entire process. The Automatic Two-Head Closed Ampoule Filling & Sealing Machine moves containers smoothly through five distinct stations to guarantee an airtight, perfectly dosed final product.
[Closed Ampoules Input] ➔ [Precise Flame Opening] ➔ [Dual Nitrogen Purging] ➔ [Two-Head Volumetric Dosing] ➔ [Hermetic Pull-Sealing] ➔ [Contamination-Free Discharge]
1. Thermal Ampoule Opening
Pre-sealed D-type glass ampoules are loaded onto the machine’s feeding hopper and feed smoothly onto a synchronized star-wheel or rack transport system. As they move into the opening station, precisely calibrated LPG and Oxygen burner nozzles apply localized heat to the top tips of the closed ampoules, cleanly opening them without generating glass micro-dust or thermal fractures.
2. Dual-Stage Nitrogen Purging (Pre-Filling)
Many injectable medications and cosmetic serums are highly sensitive to oxidation. To guarantee product stability and shelf-life, the machine features integrated pre-filling gas flushing needles. These nozzles inject medical-grade Nitrogen into the freshly opened ampoule, displacing atmospheric oxygen and establishing an inert environment before any liquid is introduced.
3. High-Accuracy Two-Head Volumetric Filling
The machine features two synchronized, heavy-duty volumetric piston pumps that draw liquid from a centralized sterile product holding tank. The dual-head configuration discharges the exact liquid dose into two ampoules simultaneously. Micro-adjustments can be made to fine-tune filling volumes from 0.5ml up to 5ml (with scaling options available up to 25ml). The filling nozzles are engineered with a diving mechanism and bottom-up fluid delivery profile to prevent choking, splashing, and neck contamination.
4. Post-Filling Purging & Hermetic Sealing
Immediately following the liquid discharge, a second round of Nitrogen purging can be applied to eliminate any residual air trapped in the neck. The ampoules then pass directly into the sealing station. Pre-heating burners soften the glass neck, while the final sealing burners melt the tip. A mechanical pulling jaw smoothly grips and removes the waste glass tip, fusing the top into a perfect, uniform, and hermetically sealed dome.
5. Automated Contamination-Free Discharge
Once the hermetic seal is complete, the finished ampoules are gently guided via a progressive discharge rack into a vertical tray collection unit. This collection is achieved completely without human intervention, preventing structural impact, minimizing glass breakage risks, and preserving the sterile integrity of the batch.
Key Technical Attributes & Structural Excellence
- Premium cGMP Construction: All component parts that come into contact with the sterile liquid are manufactured from superior Grade SS 316L stainless steel. The external frame, conveyor tracks, and non-contact surfaces are constructed from durable, easy-to-clean SS 304, allowing for seamless washdowns and sanitization.
- Optimized Two-Head Production Throughput: By utilizing a dual-head filling design, this machine achieves an efficient output range of 60 to 90 ampoules per minute (depending on liquid viscosity and glass dimensions). It effectively doubles the productivity of single-head alternatives while maintaining a highly compact cleanroom footprint.
- “No Ampoule – No Fill” Safety Interlock: Integrated proximity sensors continually monitor the tracking line. If an ampoule is missing from a slot or is improperly opened, the corresponding volumetric dosing pump will not actuate. This prevents chemical waste, minimizes cleanup downtime, and protects the machinery layout.
- Precise Flame Control & Gas Flowmeters: The heating and sealing stations are outfitted with individual flowmeters for LPG, Oxygen, and Nitrogen gases. This allows operators to meticulously control flame intensity, ensuring uniform, aesthetically perfect glass seals without charring or warping.
Targeted Industrial Applications
The sterile, high-precision processing capabilities of this two-head closed ampoule system make it a critical asset across several high-stakes industries:
- Pharmaceutical Injectables: Ideal for packaging small-volume parenterals (SVPs), intravenous drugs, anesthetics, vaccines, and liquid antibiotics requiring an absolute sterile barrier.
- Advanced Cosmeceuticals: Perfect for high-potency skincare solutions, pure vitamin serums, anti-aging concentrates, and essential hair oils packed in unit-dose glass containers.
- Chemical & Laboratory Reagents: Suited for volatile chemicals, standard calibration solutions, and analytical reagents that must remain strictly isolated from oxygen and moisture.

Frequently Asked Questions
How does the machine open the pre-sealed glass tips?
The machine features an integrated Ampoule Opening Station located before the filling zone. As the ampoules move along the transport system, a precision flame burner softens the glass tip, which is then mechanically clipped or removed. This process is synchronized so the ampoule is only open for a few seconds during the nitrogen flushing and filling stages, minimizing any exposure to the cleanroom environment.
What is the production capacity of the Two Head Closed Ampoule model?
The Two Head configuration is an ideal solution for pilot plants, clinical trials, and small-to-medium scale production. Depending on the ampoule size (typically 1ml to 10ml) and the viscosity of the liquid, this machine can achieve a consistent output of 30 to 50 ampoules per minute (approximately 1,800 to 3,000 per hour). It offers professional-grade automation with a compact footprint.
How does the machine ensure dosing accuracy and prevent wastage?
To meet strict pharmaceutical standards, the machine is equipped with:
High-Precision Filling: Two volumetric SS 316L syringes or peristaltic pumps provide a filling accuracy of ±1%.
No Ampoule – No Fill: A sophisticated sensor system ensures the pumps only activate when an ampoule is present, preventing the loss of expensive medicinal liquids.
Nitrogen Gassing: Integrated pre- and post-filling nitrogen flushing stations displace oxygen to ensure the long-term stability and shelf life of the product.
