Bulk and “ready-to-fill” format
Gx® bulk staked-in needle syringes 2.25 ml are washed, sterilized, and filled by the customer. For this form, there is a division of labor between the primary packaging manufacturer and the pharmaceutical industry where we provide the unsterilized syringe bodies in flat trays (Rondo trays).

Gx RTF® needle syringes are washed, siliconized, pre-assembled with needle shields and sterilized with ethylene oxide (EtO) by Gerresheimer Medical Systems. This means we deliver the prefillable glass needle syringe completely prepared for aseptic filling.

Gx RTF® staked-in needle syringes 2.25 ml are packed in nests (100 nest, 10x10) for easy handling and filling. These nests are suitable for all usual filling systems.


Various needle shields
The needle shield protects the cannula against deformation up to injection, and keeps the cannula sterile until use. Our Gx RTF® staked-in needle syringes 2.25 ml are available with Flexible Needle Shields (FNS), Rigid Needle Shields (RNS), as well as proprietary solutions like the Gx TERNS® (Thermoplastic Elastomer Rigid Needle Shield) exclusively developed and supplied by Gerresheimer.
