Pre-filled syringes: Syntegon inspection technology fully meets production needs

In the post-pandemic era, the demand for pre-filled syringes continues to increase. Especially in the vaccines industry, the containers are a popular choice for product packaging. The syringes are pre-filled with medication and offer multiple advantages, such as ease of use, fast injection efficiency, and the ability to avoid contamination, thus generating less medical waste, including defective products. For this to succeed, a thorough inspection of all essential syringe components is key. Solutions such as the AIM platform offer valuable support – and are being used successfully by the customer Jiangsu Jindike Biotechnology.

Although the advantages of pre-filled syringes are obvious, there are challenges that make packaging and transportation more demanding: compared to other container types, syringes are more complex, since they comprise more sensitive components, such as needles, luer locks, plunger rods, and movable plungers. All these elements call for precise inspection. Pre-filled syringes are also more expensive than vials because they require more intricate and costly packaging processes, including additional handling procedures like filling, de-/re-nesting, and rod insertion. Moreover, the inspection process for pre-filled syringes, in addition to their filling and stoppering, is more comprehensive compared to the procedures for vials.

As shown in the picture on the right, the detection applications of pre-filled syringes go beyond foreign particles inside the container and cosmetic defects like scratches on the outside. Thorough pre-filled syringe inspection further involves the needle shield, plunger, and flange, making pre-filled syringe inspection a highly complex process. To cope with these advanced requirements, Syntegon offers the proven automated inspection platform AIM as a reliable solution.
