The document describes a liquid vial filling line solution for sterile filling of vials for parenteral purposes. The major components of the line include an ultrasonic vial washing machine, sterilization tunnel, liquid filling and stoppering machine, capping machine, and visual inspection conveyor. The filling machine uses a peristaltic pump to fill vials with liquid through nozzles while purging with nitrogen before and after filling. Stoppers are fed into the machine using a vacuum suction mechanism. The line offers high precision filling accuracy, low breakage rates, and is a cost-effective solution customizable to client needs.
