High-Precision Automatic Syringe Filling and Stoppering Machine
Our fully automatic syringe filling and stoppering machine is engineered for high-precision liquid dosing and bubble-free vacuum stoppering of prefilled syringes. Designed specifically for pharmaceutical, biopharmaceutical, and medical aesthetic applications, this compact system delivers unmatched reliability while strictly complying with cGMP, FDA, and EU Annex 1 standards.
Key Advantages & Technical Features
High-Precision Dosing: Equipped with servo-driven ceramic or peristaltic pumps to ensure consistent accuracy within ±1%
Vacuum Stoppering Technology: Advanced vacuum-assisted rubber stopper insertion eliminates head-space air bubbles and prevents oxidation of sensitive active ingredients.
Gentle Nest Handling: Specially designed mechanical grippers handle nest-packed syringes smoothly, preventing friction, glass breakage, or surface scratches.
Process Workflow & Technical Specifications
1. Manual De-Bagging (MANUAL DE-BAGGING) Operators manually remove the pre-sterilized tubs/troughs from protective sterile bags in a Class C cleanroom area, preparing the nest-packed syringes for cleanroom transfer and automated processing.
2. Automatic Prefilled Dosing (AUTOMATIC PREFILLED DOSING)
Under Class A laminar flow, high-precision servo-driven pumps accurately dose the sterile liquid product into the pre-sterilized syringes with ±1% volumetric accuracy.
3. Vacuum Stoppering & Closing (AUTOMATIC PFS STOPPERING & CLOSING)
Rubber stoppers are inserted automatically using vacuum-assisted technology, completely eliminating headspace air bubbles and securing an airtight, sterile seal to guarantee drug shelf-life integrity.

FAQ: Frequently Asked Questions
Q1: What is a syringe filling and stoppering machine?
A: A syringe filling and stoppering machine is an automated, aseptic pharmaceutical packaging equipment designed to precisely dose liquid or gel products into pre-sterilized syringes (PFS) and immediately insert rubber stoppers to secure a sterile seal.
Q2: What types of liquids can a syringe filling and stoppering machine process?
A: These machines handle a wide range of pharmaceutical and cosmetic liquids, including vaccines, biopharmaceuticals, peptides (e.g., GLP-1, insulin), hyaluronic acid, dental gels, and veterinary formulations.
Q3: How does vacuum stoppering work, and why is it essential?
A: Vacuum stoppering creates a temporary vacuum inside the syringe barrel before placing the rubber stopper. This process completely eliminates headspace air bubbles, prevents product oxidation, and ensures consistent stopper positioning for high-viscosity or oxygen-sensitive drugs.
Q4: What filling pump options are available for syringe filling machines?
A: The most common options are ceramic rotary piston pumps (ideal for high-precision, low-shear, and non-drip liquid dosing) and peristaltic pumps (ideal for single-use, cross-contamination-free single-pass operations).
Q5: What is the dosing accuracy of your automated syringe filling machine?
A: Our machines utilize high-precision servo drives to achieve filling accuracy within ≤±1%, minimizing costly liquid waste-especially critical for high-value biopharmaceuticals.
Q6: Does the syringe filling and stoppering machine comply with cGMP and FDA standards?
A: Yes. All contact parts are made of 316L stainless steel, medical-grade PTFE, or advanced ceramics. The machine complies fully with cGMP, FDA 21 CFR Part 11, and EU Annex 1 regulations for aseptic processing.
Q7: Can this machine handle different sizes of prefilled syringes?
A: Yes. By changing quick-release format parts, the machine can process standard nest-packed syringes ranging from 0.5 ml to 20 ml with minimal downtime.
Q8: What is the average lead time and installation requirement for a custom machine?
A: Standard manufacturing lead time ranges from 60 to 90 days depending on custom options. The system requires standard cleanroom power/compressed air utilities and undergoes complete Factory Acceptance Testing (FAT) before shipment.
