Reliable Vial Filling Line Manufacturer

LIENM delivers purpose-built vial line machines that adapt to the evolving needs of pharmaceutical manufacturers. From liquid to powder, bulk vials to RTU formats, our vial filling lines are designed for accuracy, sterility, and compliance across every production stage.

Whether you’re setting up a compact unit or a high-output vial packaging line, our systems integrate precision filling, secure capping, and intelligent inspection—all aligned with cGMP and 21 CFR Part 11 standards. Backed by advanced drive and dosing technologies, LIENM machines ensure consistent results and long-term reliability.

Engineered according to cGMP standards, the system ensures consistent quality, effective mixing of oil and water phases, and reduced risk of contamination throughout the production cycle. Each unit can be customized based on your batch size and formulation needs, ranging from pilot-scale to full-scale production.

  • No vial – no fill
  • Supports liquid and lyophilized stoppers
  • Multiple dosing options (peristaltic, rotary piston, customized).
  • Servo-driven dosing with ±0.05% accuracy
  • Inline weight check, stopper inspection, and crimp verification
  • Integrates with RABS, isolators, laminar flow
  • Quick size changes, easy cleaning
  • Meets cGMP, FDA, and UL/CE standards

Frequently Asked Questions

1. What is a Vial Filling Line?

A vial filling line is an automated system used to wash, sterilize, fill, and seal vials in pharmaceutical, biotech, and cosmetic manufacturing. It ensures high accuracy, sterility, and compliance with GMP standards.

2. What are the main components of a vial filling line?

A complete vial filling line typically consists of the following key equipment to ensure thorough cleaning, sterilization, accurate filling, and secure packaging:

  • Vial Washing Machine (internal & external): This machine thoroughly cleans both the inside and outside of vials, removing dust, residues, and contaminants to prepare them for filling.

  • Depyrogenation Tunnel (Sterilizing Tunnel): This tunnel sterilizes the vials using high temperature and/or steam to eliminate pyrogens and microorganisms, ensuring microbiological safety of the product.

  • Liquid Filling and Stoppering Machine: An automated system that precisely fills each vial with the required volume of liquid and places the stopper to seal the vial.

  • Capping or Crimping Machine: This machine securely fixes metal or plastic caps onto the vials by crimping or pressing, preventing leaks and contamination.

  • Inspection System (manual or automatic): A station or system that inspects vials visually or using sensors to detect defects such as underfilled vials, contamination, or improperly sealed caps.

  • Labeling and Packaging Equipment: Automated equipment that applies product labels and performs final packaging to ensure product traceability and professional presentation.

3. What types of vials can be processed?

Our vial filling lines are designed to accommodate a wide range of vial types, including:

  • Glass and plastic vials

  • Sizes typically from 2 ml up to 100 ml or larger

  • Both liquid formulations and lyophilized (freeze-dried) products

  • Flexible configurations with interchangeable parts to adapt to various vial shapes and sizes

4. What types of filling systems are available?

Depending on the product’s characteristics, our vial filling lines can be equipped with different filling systems to meet various production needs:

  • Peristaltic pump filling: This system is ideal for sterile liquids and sensitive pharmaceutical products because it provides gentle, contamination-free filling by using flexible tubing. It ensures high precision and reduces the risk of product degradation or contamination.

  • Piston pump filling: Suitable for viscous or thicker products, such as gels, creams, or suspensions. The piston pump delivers accurate volume control and stable flow, making it perfect for products that require consistent dosing even with higher viscosity.

  • Time-pressure filling: This method uses controlled pressure and filling time to accurately dispense liquid volumes. It works well for low to medium viscosity liquids and provides fast and repeatable filling, minimizing product waste.

  • Vacuum filling system: Often used for delicate products or when avoiding air inclusion is critical. Vacuum filling creates a pressure differential to gently draw the product into vials, ensuring high accuracy and product integrity.

5. What quality control features are included?

Our vial filling lines come equipped with comprehensive quality control systems to ensure product integrity and compliance, including:

  • 100% in-process weight verification to confirm accurate fill volumes for every vial.

  • No-vial-no-fill detection to prevent filling errors and product wastage.

  • Advanced sensor monitoring to check the presence and correct positioning of vials, stoppers, and caps throughout the process.

  • Optional automatic rejection mechanisms that remove any faulty or defective vials to maintain batch quality.

6. Are your lines compliant with GMP and regulatory standards?

Yes, all our vial filling systems are designed and manufactured in strict accordance with international regulatory requirements, including:

  • GMP (Good Manufacturing Practices) ensuring hygiene, safety, and consistency.

  • FDA and EMA guidelines relevant to pharmaceutical manufacturing.

  • 21 CFR Part 11 compliance for electronic records and signatures, supporting secure and auditable data management.

7. Can the vial filling line be customized?

Absolutely. We understand that different customers have unique production needs, so we offer extensive customization options such as:

  • Adaptation to various vial sizes, shapes, and output capacities.

  • Selection of filling system types and number of filling heads based on product viscosity and production speed.

  • Integration into existing cleanroom environments and production lines.

  • Optional advanced modules including nitrogen purging for oxygen-sensitive products, CIP (Cleaning-in-Place) and SIP (Sterilization-in-Place) systems for hygienic maintenance, and robotic automation for handling and packaging.

8. Do you provide installation and training?

Yes, we offer comprehensive support services to ensure smooth implementation and operation, including:

  • On-site installation, setup, and commissioning by experienced engineers.

  • Hands-on operator and maintenance training programs tailored to your team’s needs.

  • Assistance with validation and documentation, including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).

  • Reliable after-sales service and readily available spare parts to minimize downtime.
