A system that fills multiple containers includes a filter with an inlet port and multiple outlet ports. The outlet ports are pre-attached to containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines is connected to a respective container interior. All of the respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. The system can produce batches of multiple sterile containers with sterile medicament in the containers.
