Aseptic filling line is used to fill the sterile solution into required container. Commonly used containers are ampoules, vials, BFS bottles and IV bags. Filling line is used according to packaging container and automated equipment is preferable for large production.

The process of filling starts with introduction of sterile solution into filling line. The packaging containers are moved towards filling line by conveyor, where precise amount of solution is filled into the container by the help of filling nozzles. Some nutritional formulations like glutathione are sensitive so they are lyophilized to keep them stable throughout the shelf life after filling them into the vial. Lyophilizer is incorporated with vial filling line to provide seamless production.

Sealing:
