A spring-free, passive safety device for 2.25mL pre-filled syringes, designed for simple assembly and use.
- Suitable for higher volume and higher viscosity formulations
- User confidence with an unobscured full drug 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

Maintains sterility in assembly – plunger is fixed 2mm away from the stopper. The device design helps to address the potential risk of container closure integrity (CCI).
Large, ergonomic plunger head and a smooth, finger flange, resulting in an integrated look and feel.
SIMPLE FINAL ASSEMBLY
Final assembly process is simple and outside of the sterile filling area. The plunger rod does not screw into the stopper.
Syringe barrel is unobscured, allowing the user to check the contents of the syringe, and to confirm the full dose has been delivered. UniSafe cannot be reused or prematurely activated.
Passive needle retraction means that the device is safe as soon as the plunger is fully depressed.
No risk of pre-activation in transit, manufacturing and removal from packaging.
Designed to work with standard, 2.25 pre-filled syringes both cropped and small round flange
providing choice of primary container.
Plunger rod cannot be pulled out when removing the RNS or the device from packaging, eliminating risk of accidental drug spillage and compromised sterility.
