Disposable 3ml Glass Cartridge | Type I Borosilicate | Standard Specification for Insulin & Dental Anesthetic Pen Injectors
Precision Primary Packaging for Self-Administration Injectable Drugs
In the evolving landscape of pharmaceutical drug delivery, self-administration has emerged as a cornerstone of modern patient care. The glass cartridge—a precision-engineered primary packaging component—serves as the critical interface between the drug product and the patient, ensuring accurate dosing, drug stability, and safe administration. At Vialab Pharmaceutical Packaging Co., Ltd. , we manufacture high-quality disposable 3ml glass cartridges designed to meet the stringent demands of insulin therapy, dental anesthesia, and other injectable pharmaceutical applications. Engineered from Type I borosilicate glass to standard specifications and compatible with leading pen injector systems, our cartridges deliver the chemical durability, dimensional precision, and container closure integrity essential for patient-safe drug delivery.
Type I Borosilicate Glass: The Material Science Behind Drug Stability
The pharmaceutical industry recognizes Type I borosilicate glass as the gold standard for parenteral packaging. Our 3ml cartridges are manufactured from neutral borosilicate glass (COE 5.0 expansion family), a material composition that offers exceptional hydrolytic resistance and minimal interaction with drug products.
The chemical inertness of borosilicate glass is particularly critical for biologics, insulin, and peptide therapeutics, where even trace levels of extractables and leachables can compromise drug stability and patient safety. SCHOTT Pharma’s FIOLAX® Type I borosilicate glass, widely recognized as the industry benchmark, provides strong levels of chemical resistance for high drug stability, increasing a drug’s shelf life to ensure it remains 100% effective when required. Our cartridges are manufactured to comparable quality standards, ensuring that the drug product remains stable throughout its shelf life—from fill-finish to patient administration.
Borosilicate glass also offers superior thermal shock resistance, a critical property for drugs that require cold chain storage or temperature excursions during transport. The low coefficient of thermal expansion ensures that the cartridge maintains its structural integrity across a wide temperature range, protecting the drug product from contamination and degradation.
Standard Specifications: ISO 11040 and ISO 13926 Compliance
Regulatory compliance is non-negotiable in pharmaceutical packaging. Our 3ml glass cartridges are manufactured to meet the most stringent international standards:
- ISO 11040-4 (2024) – Prefilled syringes – Part 4: Glass barrels for injectables and sterilized subassembled syringes ready for filling
- ISO 11040-1:2015 – Prefilled syringes – Part 1: Glass cylinders for dental local anesthetic cartridges
- ISO 13926-1 – Pen systems – Part 1: Glass cylinders for pen-injectors for medical use
- USP <660> – Glass containers for pharmaceutical use
- European Pharmacopoeia 3.2.1 – Glass containers for pharmaceutical use
- cGMP compliance throughout manufacturing
The ISO 11040 series defines the materials, dimensions, and test methods for glass cylinders used in prefilled syringes and cartridges. FDA recognizes ISO 11040-4 as a consensus standard for medical devices, supporting regulatory submissions for injectable drug products. Our cartridges conform to these internationally recognized standards, providing pharmaceutical companies with the regulatory confidence required for global market access.
Precision Dimensions: 3ml Standard Configuration
Our 3ml glass cartridges are manufactured to precise dimensional specifications that ensure seamless compatibility with leading pen injector and autoinjector systems. The standard dimensions are as follows:
| Specification | Value |
|---|---|
| Nominal Volume | 3.0 ml |
| Outer Diameter | 11.6 mm |
| Height (Total Length) | 62.3 mm |
| Material | Type I Borosilicate Glass (COE 5.0) |
| Color | Clear |
Dimensions conform to ISO 11040 and ISO 13926 standards
The standardized dimensions of our cartridges ensure consistent performance in automated fill-and-finish lines, reducing container-induced downtime and lowering reject rates of the final drug product. Uniform dimensional tolerances and high cosmetic quality enhance line efficiency, resulting in increased output and reduced total cost of ownership for pharmaceutical manufacturers.
Designed for Pen Injector and Autoinjector Compatibility
As self-administration becomes increasingly important in modern therapies, glass cartridges with pens or autoinjectors have significantly enhanced the healthcare experience of patients. Our 3ml cartridges are specifically engineered for compatibility with:
- Pen injectors – Reusable and disposable pen systems for insulin and GLP-1 therapies
- Autoinjectors – Spring-driven devices for self-administration of biologics
- Wearable injectors – Patch pumps and body-worn delivery systems
The cartridge system offers distinct advantages over traditional vial and syringe packaging. When loaded into a pen injector, the cartridge allows patients to self-administer precise doses with minimal handling, reducing the risk of dosing errors and improving treatment adherence. The standardized 3mL format is the industry standard for insulin pen systems, compatible with devices from leading manufacturers.
Container Closure Integrity: Rubber Stopper and Aluminum Seal
The integrity of the container closure system is critical for maintaining drug sterility and stability throughout the product shelf life. Our 3ml cartridges feature a robust closure system consisting of:
Rubber Plunger (Stopper) – Manufactured from bromo-butyl rubber, the plunger is specifically formulated for compatibility with anesthesia drugs and insulin formulations. The rubber material provides an effective seal between the drug product and the external environment, preventing contamination and maintaining sterility. Available washed with Water for Injection (WFI), siliconized, and ready for sterilization.
Aluminum Seal with Liner – The aluminum seal provides a tamper-evident closure that securely retains the rubber plunger within the cartridge. The liner, made of bromo-butyl rubber, ensures a gas-tight seal that prevents drug leakage and maintains container closure integrity. The seal is washed, dry, free of particles, and assembled in cleanroom environments (Class 10,000) to ensure pharmaceutical-grade cleanliness.
This dual-component closure system ensures that the drug product remains protected from contamination, moisture, and oxygen ingress throughout its shelf life—a critical requirement for sensitive biologics and peptide therapeutics.
Quality Assurance: ISO and GMP Compliant Manufacturing
At Vialab, quality is embedded in every stage of production. Our manufacturing facilities operate under strict quality control systems compliant with ISO 9001 and cGMP standards.
100% dimensional and visual inspection ensures that every cartridge meets the exacting specifications required for pharmaceutical packaging. High cosmetic quality—including the absence of surface defects, scratches, and dimensional variations—reduces the amount of rejects and ensures consistent performance in automated filling lines.
Our advanced production lines feature Italian SPAMI and German Amberg forming machines, delivering high-capacity production with exceptional dimensional accuracy. The production process includes:
- Automatic feeding of glass tubing
- Precision glass molding
- Online dimensional inspection
- Foreign body removal
