Prefilled Glass Syringe

A prefilled glass syringe (PFS) allows injectable drugs to be delivered in a single step. It combines the functions of a pharmaceutical vial and a disposable syringe, saving time by reducing steps in the process. A prefilled glass syringe is a small system consisting of a barrel, a plunger, a plunger rod, or a piston. The syringe may be supplied with a barrel cone and closure type that supports the attachment of a suitable needle later when the injection is administered, or alternatively, the syringe may be manufactured with a pre-attached needle and a protective needle shield. Prefilled glass syringes are used in many different applications and settings, ranging from pediatric vaccines administered at a doctor's office, to ophthalmic treatments available at specialist clinics and long-term therapies for chronic conditions that patients can use at home.
