A full range of components for prefilled syringes

Plunger rods

Our plunger rods are engineered for precision, robustness, and smooth gliding, ensuring reliable drug administration. Available in various lengths, diameters, and materials (including sustainable alternatives), they are manufactured under ISO 13485 and MDR-compliant protocols for critical applications such as vaccines and biologics.
