Vetter-Ject is a syringe closure system for filling highly sensitive compounds
Vetter Pharma International, based in Germany, has developed an injection moulded syringe closure system for highly sensitive compounds.
Vetter-Ject is a tamper-evident closure system for prefilled syringes, which combines with an integrated staked needle for extra safety and security. The syringe closure system is partly produced by means of two-component injection moulding of polypropylene and thermoplastic elastomer.
The baked-in siliconisation of the needle for the glass barrel means less silicone oil than normally used is necessary, making Vetter-Ject particularly suitable for silicone-sensitive drug products. The silicone content of the syringe can also be adjusted according to the requirements of the customer, said Vetter. The company claims the amount of silicone used, as well as the related particle load, can be reduced by up to 80% when compared to the standard siliconisation process applied to conventional syringe systems.
Vetter-Ject is supplied with an integrated needle that is simple to handle and user-friendly. “The tamper-evident closure enables that any attempt at opening of the closure system will be immediately and permanently visible to the naked eye,” said Vetter.
This feature is activated when the needle shield is removed and plastic bridges are broken, preventing any potential misuse or reuse.
Vetter-Ject can be used with a wide range of primary packaging options including different stoppers and glass barrels, which can be customised according to the needs of the drug product.
The closure’s design won recognition in Germany’s two prestigious product design programmes, the iF Design Awards and the Red Dot Design Awards.
“The fact that two eminent juries recognise the novel attributes of Vetter-Ject, clearly demonstrates the full potential of our innovation,” said Thomas Otto, managing director at Vetter.
