Description

Ampoule Filler for Biological Indicator is a specialized machine designed for filling and sealing glass ampoules used in biopharmaceutical, biotech, and sterilization validation applications. These machines ensure precise filling of biological indicators, typically containing microorganisms like Geobacillus stearothermophilus spores, into ampoules for monitoring sterilization processes, such as steam or hydrogen peroxide sterilization.

Loading: Empty, sterilized ampoules are fed from a hopper onto a traveling rack (in formats of 1, 2, 4, or 8).

Nitrogen Purging: Inert gas (nitrogen or argon) is flushed to remove oxygen.

Filling: Precise liquid volumes (e.g., nutrient broth with spores) are dispensed via filling needles.

Post-Nitrogen Flush: Additional nitrogen flushing to ensure an inert environment.

Pre-Warming and Sealing: Ampoules are warmed with a low-pressure flame, then sealed using high-precision burners and rollers for uniform closure.

Collection: Sealed ampoules are collected upright on a tray for further processing or testing.

Certified for use in steam, ethylene oxide, or hydrogen peroxide sterilization validation.

Working Principle of Ampoule Filler for Biological Indicator

Empty washed & sterilized ampoules loaded onto infeed hopper of the machine. From where it has been received to receiving rack through starwheel/cassette. The moving rack which moves horizontally collect one/two/four/eight ampoules from the receiving rack and transfer the ampoule to the machine in left to right in an inclined position. During ampoule movement Pre-gassing, Filling, Post Gassing, Pre-heating & Sealing Station perform filling and sealing operations. At the end duly filled and sealed ampoules get collected automatically onto collection tray of the machine.

Key Features of Ampoule Filler for Biological Indicator

Purpose: Fills and seals ampoules with biological indicators, which are used to validate or monitor sterilization processes by confirming the elimination of resistant microorganisms. These ampoules often contain a nutrient broth, pH indicator, and spores, sealed to prevent contamination.

Design: Typically a monobloc system combining filling and sealing on a single platform, ensuring efficiency and compliance with cGMP standards. Constructed from high-quality stainless steel (e.g., 316L) for durability and hygiene.

Filling Mechanism: Operates on a volumetric piston-pump principle, delivering precise liquid volumes (0.5ml to 25ml in single dosing) into ampoules ranging from 1ml to 30ml in capacity. Some models handle smaller sizes, like 0.4ml mini spore ampoules, or specialized forms like onion skin ampoules.

Nitrogen Flushing: Features pre- and post-nitrogen flushing units to purge oxygen, minimizing contamination and ensuring an inert environment inside the ampoule.

Sealing Process: Includes pre-warming and sealing stations using oxygen and LPG (propane) flames. Specially designed rollers rotate ampoules for uniform sealing, with burners suited for glass thicknesses (e.g., 0.3mm to 0.8mm for onion skin tubes). A dead-tray system ensures upright collection of sealed ampoules.

Capacity and Speed: Can fill and seal 10 to 250 ampoules per minute, depending on the model (e.g., single, two, four, six, or eight-head configurations). High-speed models can process up to 12,000 ampoules per hour.

Applications: Used for filling biological indicator ampoules, crushable glass tubes, or onion skin tubes for pharmaceutical, biotech, cosmetic, and chemical applications, including agro-insecticides and veterinary medicines.

Additional Features:
- Minimal change-over time for different ampoule sizes.
- Pre-heating units for thick glass ampoules to ensure proper sealing.
- Safety features like pressure reducers and stainless steel hoods to vent fumes.
- Compact cGMP-compliant models with options for laminar airflow or isolators for sterile environments.

Examples:
- Machines offer flexibility for filling 1ml to 30ml ampoules with precise dosing and nitrogen flushing, suitable for biological indicator production.
- Onion Skin Ampoule Fillers are custom-designed for thinner, crushable tubes used in specific biological indicator applications, with a filling accuracy of 1%.

FAQ for Ampoule Filler for Biological Indicator

What is an Ampoule Filler for Biological Indicator?

An Ampoule Filler for Biological Indicator is a specialized cGMP-compliant monoblock machine designed for precise filling and hermetic flame sealing of glass ampoules containing spore suspensions (such as Geobacillus stearothermophilus in nutrient broth). These ampoules are used as Biological Indicators (BIs) to validate sterilization processes like steam, ethylene oxide, and hydrogen peroxide. The machine supports both standard and onion-skin ampoules (thin-walled, crushable tubes) with gentle handling to ensure sterility and product integrity.

Which ampoule sizes and production capacities does the machine support for Biological Indicators?

The machine handles ampoule sizes from 1 ml to 30 ml (model dependent), including small-volume and mini spore ampoules as well as thin-walled onion-skin ampoules. Available models: AFS-1, AFS-2, AFS-4, and AFS-8 heads.

AFS-1: Up to 25 ampoules/min
AFS-2: Up to 50 ampoules/min
AFS-4: Up to 100 ampoules/min
AFS-8: Up to 200 ampoules/min (max. 12,000 ampoules/hour)

Filling accuracy is ±1% with volumetric piston pumps, making it ideal for consistent spore population in every BI ampoule.

Why is nitrogen flushing important in an Ampoule Filler for Biological Indicators?

Nitrogen flushing (before filling, during filling, and after filling) removes oxygen and creates an inert environment inside the ampoule. This prevents oxidation of the sensitive spore suspension, avoids contamination, and enhances the stability and shelf life of the Biological Indicator. Neck-centering during flushing ensures effective purging, which is critical for maintaining the certified resistance characteristics of the spores.

What safety and quality features does the Ampoule Filler for Biological Indicator include?

Key features include:

“No Ampoule – No Filling” and “No Ampoule – No Seal” interlocks to prevent wastage and errors.
