2High-quality Controlled Manufacturing Processes

Product Introduction

COC/COP prefilled syringes are a new type of liquid drug packaging, with the medication preloaded in the container. The syringe features a Luer connection at the tip, allowing injection simply by attaching or twisting on the needle. Compared with traditional glass syringes, they are lighter, more impact-resistant, less prone to breakage, highly transparent, chemically stable, and reduce extractables, enhancing medication safety

High-quality Controlled Manufacturing Processes

Product Applications

Biologics (GLP-1, hormones, monoclonal antibodies, etc.)
