Pre-filled syringe

Key Elements and Functional Attributes

The main components of a pre-filled syringe filling machine include:

Feeding System: This system feeds the RTU (ready-to-use)sterilized syringes (usually in trays or bags) into the machine. Manual or fully automatic unpacking is available. It is used to aseptically remove the syringes from the packaging, ensuring a completely sterile operation.

Filling Station: Multi-needle filling heads inject the drug solution into each syringe. A high-precision ceramic plunger pump is used, and the number of filling heads can be selected from 1, 2, 5, 10, etc. It features full servo control, vacuum filling, and adjustable vacuum levels.

Stopping/Sealing Unit: After filling, the syringe enters the stoppering station, where a rubber stopper is inserted into the syringe barrel. This station typically uses a vacuum-assisted or plunger mechanism to secure the rubber stopper, and then checks the seal integrity.

Aseptic Control: All fluid channels and internal surfaces are made of stainless steel (typically 316L) for easy cleaning and are designed for CIP (clean-in-place) and SIP (sterilize-in-place) cleaning. The filling area is maintained in ISO 5 (Class A) clean air, typically isolated by isolators or RABS (Restricted Access Barrier Systems) to maintain sterility.

Syringe filling machine workflow

A vision system detects syringe orientation or confirms piston presence.

Control electronics: A PLC/HMI synchronizes all operations with servo-driven motion. A touchscreen interface controls formulation (fill volume, speed, etc.) and displays diagnostic information.

Inspection module: Many production lines are equipped with online inspection systems. Checkweighers or light inspection machines verify the fill volume and integrity of each syringe. Non-conforming products are automatically rejected.

All liquid-contacting parts meet pharmaceutical standards. The entire machine operates under Class 100 laminar flow, ensuring complete sterility and low risk. RTU nesting box filling is also compatible with pre-filled, cartridge, and vial packaging materials.
