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 aseptic filling 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.

Aseptic filling of sterile drugs, also known as sterile filling/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.

We are a specialist in the field of sterile filling of pharmaceuticals into vials. 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.


Symbiosis is a renowned expert in this field given that all of the products we manufacture are produced using aseptic manufacturing techniques. More specifically, we specialise in the aseptic filling of sterile drug products intended for use in clinical trials or licensed commercial supply.


Operating within dedicated cleanroom facilities at our GMP MHRA-licensed facility in Scotland, our experienced team routinely fill biological pharmaceutical products such as antibodies, proteins, peptides, DNAs, RNAs, ADCs and cytotoxic, cytostatic and highly potent APIs.


We deliver a lyophilisation service by either aseptic or low bioburden cleanroom dispensing of up to 100 litres of bulk product per batch. Whether you require a one-off batch or the ongoing bulk lyophilisation of API or finished product, our technical experts can support your supply needs.
