Built with a GMP-compliant structure, ZONESUN provides vial filling machines and related packaging system supporting automatic vial fiilling, half stoppering (suitable for process that require preparation before freeze drying) or full stoppering, flip-off caps crimping. With flexiblle configurations, ZONESUN vial filling machine can work operate as standalone unit or be intergrated into a complete vial packaging line, including downstream labeling and cartoning systems. ZONESUN vial filling machine is designed for precise liquid or powder dosing while minimizing contamination risk across laboratory, biotech, and pharmaceutical environments.
Applications of Vial Filling Machine
ZONESUN vial filling machine is widely used for:
- Vaccines
- Antibacterial Solution
- Injectable liquids
- Biotech and biological solutions
- Freeze-dried (lyophilized) products
- Laboratory and pilot-scale production

How the ZONESUN Vial Packaging System Works
The ZONESUN vial packaging system is designed to support the complete vial processing workflow before and after lyophilization.
1. Vial Feeding
Automatic vial feeding system ensures continuous and stable bottle input.
2. Liquid or Powder Filling
- Peristaltic pump dosing (liquid)
- Sscrew auger filling (powder)
- Servo-controlled filling process
- Suitable for small to medium volume applications
3.Half Stoppering & Full Stoppering
The ZONESUN vial filling machine supports both half-stoppering and full-stoppering modes, depending on production requirements.
For lyophilization applications, vials are typically processed with half stoppering to allow moisture removal during freeze drying.
For other production processes, the system can operate in full stoppering mode, enabling a continuous workflow with direct integration to the capping and crimping unit for complete sealing in one line.
4. Transfer to Lyophilization (If Required)
Vials are transferred to the freeze dryer while maintaining stopper position.
5. Post-Lyophilization Sealing
After drying:
- Final stoppering is completed
Aluminum caps are applied and crimped (via separate equipment)
ZONESUN Vial Filling System
- Peristaltic pump driven by servo motor
- Interchangable screw auger
- Stable and repeatable dosing performance
- Suitable for aqueous and sensitive liquids or powdered products
Filling Accuracy:
Up to ±1% (depending on product, tubing, and calibration)
For very small volumes, actual results may vary slightly due to tubing elasticity, filling material characteristics, and operating conditions.
Stoppering & Sealing System

FAQ of Vial Filling Machine
1. Can this vial filling machine be used for lyophilized products?
Yes. The system supports filling and half stoppering before freeze drying and can be integrated with freeze dryers.
2. How is the filling volume controlled?
Automatic models use servo-controlled peristaltic pumps for stable and repeatable dosing.
Semi-automatic models typically rely on time-based adjustment of filling duration and pump speed.
3. What is the filling accuracy?
Typically up to ±1%, depending on product properties, tubing, and calibration.
4. Is ZONESUN vial filling machine suitable for sterile applications?
Product-contact parts of the ZONESUN vial filling machine are made of SUS304 and SUS316 stainless steel. Laminar flow protection and disposable tubing help minimize the risk of contamination.
5. Can it be integrated into a production line?
Yes. It can work with upstream and downstream equipment, including vial labeling machine, and cartoning systems.
ZONESUN vial filling machine is designed to support precise and flexiblevial processing and packaging solution across a wide range of applications, from laboratory use to automated production environments.
