REDUCED RISK
No compromise to sterility in assembly – plunger does not touch the bung.

2

COMFORT
Large, ergonomic plunger head and a smooth, integrated finger flange, resulting in an integrated look and feel.

3

SIMPLE FINAL ASSEMBLY
Final assembly process is simple and outside of the sterile filling area.

4

USER CONFIDENCE
Syringe barrel is unobscured, allowing the user to check the contents of the syringe, and to confirm the full dose has been delivered.

5

PASSIVE SAFETY 
Passive needle retraction means that the device is safe as soon as the plunger is fully depressed.

6

RELIABILITY
Prevention of accidental activation e.g. in transit.

7

COST EFFECTIVE
Designed to work with standard, 2.25 pre-filled syringes both cropped and small round flange
providing choice of primary container.
