Injection ampoules filling

Small glass or plastic containers that contain sterile solutions or suspensions. These ampoules (vials) play an important role in the pharmaceutical industry as they allow for precise dosing and the maintenance of sterile conditions.

Preparation process

  1. Selection of raw materials: This is a critical choice in the process. For glass ampoules (vials), borosilicate glass is the most common, as it offers excellent resistance to temperature changes and chemicals. For plastic ampoules (vials), polypropylene or polyethylene terephthalate (PET) is used.
  2. Forming: Glass ampoules (vials) are made by melting and shaping glass tubes. The molten glass is placed into special machines that mold and size the ampoules (vials). Plastic ampoules (vials) are produced through extrusion and injection molding, where the plastic is melted and poured into molds.
  3. Sterilization: The finished ampoules (vials) are sterilized to eliminate microorganisms and ensure safe usability. For glass ampoules (vials), this is usually done through heat sterilization, while plastic ampoules (vials) are sterilized with ethylene oxide or gamma radiation.
  4. Filling and sealing: Filling machines dispense the appropriate solutions or suspensions into the sterilized ampoules (vials). It is essential to ensure that the process remains completely sterile during filling. The ampoules (vials) are typically sealed using flame sealing or crimping to create a hermetic seal.
  5. Quality control: The finished ampoules (vials) undergo strict quality control. This includes checking the contents, testing for sterility, and examining the physical integrity of the ampoules (vials).
  6. Packaging and storage: After quality control, the ampoules (vials) are placed in suitable packaging that ensures their protection during transport and storage. Considerations for packaging include light sensitivity and temperature stability.

Applicability

  • Ampoules (vials) allow for the sterile dosing of medications, which is especially important in the case of injectable preparations. This minimizes the risk of infections and ensures the effectiveness of the drug.
  • They also ensure that medications are administered in precise doses, which is particularly crucial for formulations requiring critical dosing, such as chemotherapy agents or hormonal injections.
  • The hermetic sealing of injection ampoules prevents the ingress of air and moisture, thus providing a longer shelf life for the medications.
  • Ampoules are widely used for the storage and dosing of various medications, including antibiotics, pain relievers, vaccines, and vitamins.

Did you know?

  • The first glass ampoules (vials) were developed in the late 19th century. Their use quickly spread in medicine because they ensured the sterility and stability of medications.
  • In recent years, more and more plastic ampoules have entered the market, as they are lighter and less fragile than their glass counterparts.
  • Some ampoules feature a self-breaking mechanism that allows users to open the ampoule safely and quickly with a simple motion, without the need for extra tools.
  • The techniques used for sealing ampoules, such as flame sealing, not only provide hermetic closure but also prevent users from accidentally opening or contaminating them.

Thus, injection ampoules are essential in modern medicine. They ensure the sterility, precise dosing, and long shelf life of medications, while the continuous development of manufacturing and control techniques offers even greater safety and effectiveness.
