Sterile Fill Finish




Our facility was purpose-built to meet increasing market demand for small-scale, shorter sterile drug product development timelines, while consistently maintaining regulatory compliance.




Today, we reliably support our customers with the sterile fill finish and lyophilisation of conventional, biologic and cytotoxic drugs into vials. Helping clients across the globe meet their project milestones, we provide rapid access to manufacturing slots and quick release of drug product to ensure tight timelines are successfully met.

Sterile filling of drugs, also known as sterile fill finish, remains one of the most critical processes in biopharmaceutical manufacturing. This is due to it’s highly technique driven processes and the potential safety impact to the end user, usually an already compromised patient. There are only indirect safeguards for the sterility of the filled drug after it is stoppered and capped in the cleanroom.
