The disclosed embodiment relates to a system and method for treating a non-sterile surface of at least a component of a medical device, such as, but not limited to, a cartridge for an injection device. The system for treating a non-sterile surface of a medical device includes a source of electromagnetic radiation and, in some embodiments, a source of laminar airflow. The source of electromagnetic radiation provides exposure and the source of laminar airflow provides laminar airflow to the surface for treatment of the medical device. The method for treating a non-sterile surface includes exposing the non-sterile surface of a cartridge to a pulsed electromagnetic wave. In some embodiments, simultaneous to the pulsed electromagnetic radiation exposure, a laminar airflow can be directed perpendicular to the surface of the cartridge.
