Vial Filling

Symbiosis is a specialist in the field of sterile filling of pharmaceuticals into vials. Vial filling has been our core area of technical and regulatory expertise since we opened our MHRA-licensed manufacturing facility in Scotland in 2011.

If you require a manufacturing partner to aseptically fill a liquid or lyophilised drug product into vials, then rest assured that your drug development project will be in safe hands at Symbiosis.

Whether you need to fill a 2 mL, 20 mL or 100 mL glass vial, our experienced team can support your project with all small-volume parenteral dosage sizes. Currently, our batch sizes range from a few hundred to a few thousand vials so are ideal if you need clinical trial materials or low volume commercial supplies.


Our in-house vial filling capability enables us to fill bulk volumes under 100 litres per batch, including products that require aseptic liquid filling and specialist lyophilisation. This may also include the manufacture of the following products using our dedicated cleanrooms:

  • Biologics including antibodies
  • Proteins
  • Peptides
  • DNA
  • Antibody-Drug Conjugates (ADCs)
  • Cytotoxic, cytostatic and highly potent APIs



As you would expect from a world-class CMO, our vial filling capability is supported by in-house vial washing and depyrogenation and component preparation services. Furthermore, all pharmaceutical production is undertaken within our purpose-built GMP compliant facility, which was specifically designed for the aseptic manufacturing of sterile drug products on this scale.

Regulatory compliance and the highest levels of technical capability are at the heart of everything we do, yet our agility also gives our biotech and speciality pharmaceutical clients rapid access to manufacturing slots. This focus on quality combined with operational flexibility is what sets Symbiosis apart from other CMOs.

If you are planning a sterile vial filling project, then please contact our team today. Even if the deadline is tight, our team will make every effort to help achieve your milestones and timelines.
