Automatic Single Head Closed Ampoule Filling & Sealing Machine
Precision Sterile Packaging Solutions for Closed/D-Type Glass Ampoules
In sterile pharmaceutical manufacturing, laboratory testing, and high-end cosmetic production, maintaining the total integrity of liquid injectables is a non-negotiable priority. The Automatic Single Head Closed Ampoule Filling & Sealing Machine from Harsiddh Unimach Pvt. Ltd. is engineered specifically to address the rigorous demands of processing closed-type (D-Type) glass ampoules.
By integrating the critical steps of opening, purging, precise volumetric dosing, and hermetic sealing into a singular, highly synchronized system, this equipment minimizes human intervention and drastically reduces contamination risks. Built in strict alignment with international regulatory standards, this single-head machine offers a compact footprint, exceptional dosing accuracy, and the operational flexibility required for pilot scales, specialized batch manufacturing, and research facilities.
Understanding Closed Ampoule Processing: The Ultimate Aseptic Standard
Unlike open ampoules, which can be exposed to environmental dust, particulate matter, or atmospheric moisture during transport and storage, closed or pre-sealed ampoules (commonly referred to as D-Type ampoules) arrive at the production facility hermetically sealed by the glass manufacturer. This ensures that the interior of the container remains entirely sterile until the exact moment it enters the filling line.
The single-head packaging system engineered by Harsiddh Unimach Pvt. Ltd. opens, fills, and re-seals these containers in a continuous, controlled sequence. This method provides several distinct advantages for high-value formulations:
- Maximized Sterility Assurance: Because the container is opened only seconds before the liquid is introduced and sealed immediately afterward, the window of exposure to ambient air is virtually eliminated.
- Oxidation Prevention: The system features integrated gas purging capabilities, allowing manufacturers to substitute ambient air with inert gas, thereby safeguarding sensitive formulations from chemical degradation.
- Cost-Effective Small-Batch Efficiency: While multi-head lines are optimized for mass production, this single-head system is purpose-built for premium, small-scale operations, offering minimal product giveaway and ultra-fast changeovers between different container volumes.
The Mechanical Symphony: Detailed Sequence of Operations
Efficiency in sterile packaging depends on mechanical harmony. This machine operates on a highly precise volumetric piston pump mechanism, driven by a single synchronized motor that guarantees perfect timing across every sub-assembly.
[Closed Ampoules Feed] ➔ [Precision Flame Opening] ➔ [Nitrogen Purging] ➔ [Volumetric Liquid Dosing] ➔ [Pre-Heating & Pull-Sealing] ➔ [Slanted Tray Collection]1. Automated Feeding and Mechanical Opening
Pre-sealed glass ampoules are loaded onto the feed tray, where an indexing mechanism gently guides them into the main processing line. As the ampoule advances, a dedicated, finely tuned LPG and Oxygen burner flame applies concentrated heat to the pre-sealed tip, opening the ampoule cleanly without generating glass micro-particles or structural stress fractures.
2. Advanced Nitrogen Purging (Pre-Dosing)
Before any liquid product is introduced, the newly opened ampoule moves underneath a specialized gassing nozzle. A precise burst of sterile, filtered Nitrogen gas clears the interior cavity, displacing oxygen and creating an inert micro-environment that preserves the stability, shelf-life, and chemical structure of active pharmaceutical ingredients (APIs).
3. High-Accuracy Volumetric Filling
The container indexes immediately to the single filling head. Utilizing a premium-grade volumetric piston pump, the machine dispenses the liquid dose with micro-precision. The system handles fill sizes stretching from 0.5ml up to 25ml. The filling nozzle is designed with custom diving metrics to enter the neck smoothly, executing a bottom-up fill that prevents splashing, wetting of the ampoule neck, or accidental foaming.
4. Post-Gassing, Pre-Heating, and Hermetic Sealing
Following the liquid discharge, a second post-filling Nitrogen flush can be applied to ensure no oxygen remains in the headspace. The ampoule then enters the sealing zone. It passes a pre-heating station to condition the glass before moving to the main fusion sealing nozzles. A mechanical gripper pulls away the waste glass tip while the flame melts the remaining glass, forming a smooth, rounded, completely airtight, and hermetically sealed top.
5. Systematic Collection and Classification
The finalized, sterile ampoule is smoothly discharged from the indexing wheel onto a specialized “sleepy tray” (a custom-engineered slanted collection ramp). This tray ensures that the hot glass tips cool safely without touching other containers, preventing thermal shock, reducing cosmetic scratching, and making inspection and batch collection straightforward for operators.
Core Technical Features & Premium Construction
- Sanitary Stainless Steel Architecture: To meet the strict hygiene requirements of cleanroom environments, all external panels, structural frames, and conveyor tracks are fabricated from Stainless Steel 304. All fluid path components, pistons, and filling nozzles are crafted from premium Stainless Steel 316L.
- Centralized Synchronized Drive: The entire operational sequence—from indexing and opening to filling and sealing—is driven by a centralized motor assembly. This mechanical integration ensures that the timing between the liquid delivery and the flame sealing never drifts, eliminating timing errors and container damage.
- Tool-Less Changeovers: Adapting the machine to accommodate different glass ampoule dimensions (from 1ml to 25ml) requires minimal downtime. The formatting parts are designed for quick mechanical adjustments, maximizing daily uptime.
- Comprehensive Flame Control: The machine features independent flow-control valves for the oxygen, LPG, and nitrogen lines, allowing operators to fine-tune the flame intensity and gas pressure to match varying glass thicknesses perfectly.
Cross-Industry Applications
The exceptional versatility and strict hygienic boundaries of this single-head system make it an asset across several specialized sectors:
- Pharmaceutical Injectables: Ideally suited for filling sterile clinical trials, anesthetic solutions, small-batch vaccines, vitamins, and high-potency liquid drugs.
- Advanced Cosmetics: Frequently utilized for packaging high-concentration serums, anti-aging compounds, essential skin oils, and chemical peels that require airless preservation.
- Chemical & Laboratory Standards: Perfect for sealing chemical reagents, analytical standards, and volatile laboratory samples that must be kept entirely free from atmospheric contamination.

Frequently Asked Questions
How does the machine open the pre-sealed ampoules?
The machine features an integrated Ampoule Opening Station. As the ampoule is positioned by the transport system, a precision flame burner softens the glass tip, which is then mechanically "clipped" or removed. This ensures a clean, burr-free opening immediately followed by the nitrogen flushing and filling stations to maintain maximum sterility.
What is the production capacity of the Single Head model?
The Single Head configuration is optimized for R&D, clinical trials, and small-batch production. It typically achieves a consistent output of 20 to 30 ampoules per minute (approximately 1,200 to 1,800 per hour). It offers the same high-level technology as our 8-head industrial models but in a compact, manageable footprint.
How does the machine ensure dosing accuracy for expensive pharmaceutical liquids?
To protect high-value formulations, the Harsiddh Single Head machine is equipped with:
High-Precision Filling: A volumetric SS 316L syringe or peristaltic pump system provides a filling accuracy of ±1%.
"No Ampoule – No Fill" Sensor: This electronic interlock prevents the pump from activating if an ampoule is not detected, eliminating liquid wastage.
Nitrogen Gassing: Integrated pre- and post-filling gas flushing stations displace oxygen to prevent oxidation of sensitive drugs.
What are the key cGMP and cleanroom features?
Despite its compact size, this machine is built to rigorous cGMP industrial standards:
Material Integrity: All liquid contact parts are made of SS 316L, and the exterior is polished SS 304 stainless steel.
Sterile Design: Its slim-line, linear design is specifically optimized for placement under a Laminar Air Flow (LAF) unit.
Automation: Controlled via a user-friendly PLC with a Touchscreen HMI, allowing for precise adjustment of burner flames, pump speed, and production counting.
