Automatic Ampoule Filler

Description

Pharmaceutical glass ampoules are filled and sealed using an automatic ampoule filler, also referred to as an ampoule filling machine. Our AFS series ampoule filler is made to precisely fill and seal ampoules as needed in the pharmaceutical industry. We have a variety of machine models that can manufacture between 25 and 300 ampoules per minute, depending on the needs of the consumer. With the use of various replacement parts and equipment, our machine models can fill ampoules ranging from 1 to 20 millilitres.

Depending on the needs of the user, Ampoule Filler can be set up with a variety of filling mechanisms, such as mechanical pump type filling, servo driven filling, or peristaltic pump type filling. Every one of our equipment models conforms with GMP regulations for medicines. Pre-gassing, product filling, post-gassing, pre-heating, and sealing are all done on a single platform in this monobloc-type machine. For ease of cleaning and sterilisation, all liquid contact components are constructed using AISI SS 316L materials. To prevent any potential cross-contamination, peristaltic pump style filling may be provided.

 

The sealing station operates in two stages. Preheating is done in stage one to eliminate any potential droplets from the ampoule’s inner surface. Second-stage sealing is carried out using a flame that combines LPG and oxygen. To achieve perfect dome-shaped sealing, ampoules are spun 360 degrees.

Working Principle of Automatic Ampoule Filler

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.

The operation of an ampoule filling machine follows a systematic, automated process to ensure sterility, precision, and efficiency:

  • Sterilization and Loading:
    • Empty ampoules are washed, sterilized (often in a depyrogenation tunnel), and loaded into the machine’s hopper or infeed system.
    • A starwheel or conveyor belt aligns and transports ampoules (1, 2, 4, 6, or 8 at a time, depending on the machine’s head configuration) to the processing stations.

 

  • Pre-Gassing (Optional):
    • Ampoules are flushed with nitrogen to displace atmospheric air, reducing the risk of oxidation or contamination.

 

  • Filling:
    • The filling station dispenses a precise volume of liquid or powder into each ampoule using piston or peristaltic pumps.
    • Neck centering ensures accurate filling, and diving nozzles minimize foaming.
    • In-process control (IPC) systems may weigh ampoules before and after filling to verify accuracy.

 

  • Post-Gassing (Optional):
    • Additional nitrogen flushing after filling to further protect the contents.

 

  • Pre-Warming and Sealing:
    • Ampoules move to a pre-warming station where a low-pressure flame warms the glass neck.
    • At the sealing station, a high-temperature flame (using oxygen and LPG) melts the thin glass top to create a hermetic seal.
    • Rollers rotate the ampoules during sealing for uniform closure, and waste glass tips are clipped and ejected.

 

  • Collection:
    • Sealed ampoules are collected on a tray, while defective units are rejected.
    • The process is continuous, with minimal manual intervention, ensuring high throughput and sterility.

 

The machine operates on the principle of slant traveling, where ampoules move at an inclined angle during filling and sealing to accommodate variations in neck size, thickness, and shape, ensuring consistent results.

  • AFS-4 (Four Head): Up to 100 ampoules per minute
  • AFS-8 (Eight Head): Up to 200 ampoules per minute (up to 12,000 ampoules per hour)

Higher output depends on ampoule size, product viscosity, and operator settings. The machine supports quick changeover with minimal change parts.

The machine handles glass ampoules from 1 ml to 30 ml (AFS-1 & AFS-2) and 1 ml to 20 ml (AFS-4 & AFS-8). Filling range: 0.5 ml to 30 ml in a single dose. It delivers high filling accuracy of ±1% (up to ±0.5% under optimized conditions) using piston pumps, diving nozzles, and neck centering to reduce foaming and ensure precision.

Empty, washed, and sterilized ampoules are loaded into the infeed hopper and transferred via starwheel in a slant/inclined position. The automated cycle includes:

  1. Nitrogen pre-gassing (to remove oxygen)
  2. Volumetric filling with neck centering
  3. Nitrogen post-gassing
  4. Pre-heating to eliminate droplets
  5. Flame sealing using LPG + Oxygen burners while ampoules rotate 360° for a perfect dome-shaped hermetic seal
  6. Automatic collection of sealed ampoules and ejection of glass tips

The entire process ensures sterility and protects sensitive products.
