A springless, passive safety device for 2.25mL pre-filled syringes, designed for simple assembly and use.
- Suitable for higher volume and higher viscosity formulations
- Springless design allows unobscured full dose visibility
- Simple final assembly
- Secure plunger prevents removal, spillage and repeat use
- Prevention of accidental activation
- Passive needle retraction and complete shielding
- Intuitive to use – same injection technique as UniSafe® 1mL
and a standard pre-filled syringe
- Compatible with multiple syringe manufacturers

No compromise to sterility in assembly – plunger does not touch the bung.
Large, ergonomic plunger head and a smooth, integrated finger flange, resulting in an integrated look and feel.
SIMPLE FINAL ASSEMBLY
Final assembly process is simple and outside of the sterile filling area.
Syringe barrel is unobscured, allowing the user to check the contents of the syringe, and to confirm the full dose has been delivered.
Passive needle retraction means that the device is safe as soon as the plunger is fully depressed.
Prevention of accidental activation e.g. in transit.
Designed to work with standard, 2.25 pre-filled syringes both cropped and small round flange
providing choice of primary container.
Plunger cannot detach when removing the RNS.
