Onion Skin Ampoule Filling Machine

Production capacity varies by model:

• OFS-1 (Single Head): Up to 25 ampoules per minute
• OFS-2 (Double Head): Up to 50 ampoules per minute
• OFS-4 (Four Head): Up to 100 ampoules per minute
• OFS-8 (Eight Head): Up to 200 ampoules per minute

This gives a maximum output of up to 12,000 ampoules per hour. Speed is adjustable via variable frequency drive, and actual output depends on ampoule size, fill volume, and product viscosity. It is suitable for both medium and high-volume production of thin onion skin tubes.

The machine is engineered for small, thin onion skin ampoules with diameter 6–15 mm and length 55–150 mm (minimum 7 mm diameter × 55 mm height). It supports:

• 1 ml to 30 ml ampoules (model dependent: 1 ml to 30 ml on single/double head, up to 20 ml on higher heads)
• Fill volumes from 0.5 ml to 25 ml in a single dose

It delivers ±1% filling accuracy and easily accommodates variations in glass thickness and ovality thanks to the specialized slant travel design and neck centering system.

Yes. It features pre-, during, and post-nitrogen flushing with ampoule neck centering to remove oxygen, prevent oxidation, and maintain product stability and sterility. Additional features include a “No Ampoule – No Filling” system to eliminate wastage, a pre-heating station, and precise flame sealing. All product contact parts are made of SS 316L, and the machine is fully cGMP compliant, making it suitable for sensitive liquids, biological indicators, and contamination-free processing in cleanroom environments.

Key features include:

• Specialized slant travelling mechanism designed for thin & crushable onion skin ampoules
• Volumetric piston pump filling with ±1% accuracy
• Multi-stage nitrogen flushing (pre, during & post) with neck centering
• Pre-heating station and accurate LPG + Oxygen flame sealing with flow meters
• “No Ampoule – No Filling” system and dead tray for rejected ampoules
• SS 316L contact parts and compact cGMP-compliant design
• Minimum changeover time, easy cleaning, and low maintenance

Benefits: Gentle handling to prevent breakage of delicate thin glass, high-speed production, excellent dosing precision, superior sterility assurance, reduced product wastage, hermetic sealing for longer shelf life, and minimal human intervention. Optional PLC/HMI, servo filling, peristaltic pumps, and laminar airflow are also available.
