Pen Injector Cartridges – 1.8ml & 3ml Type I Borosilicate Glass for Autoinjectors & Pens
Precision Primary Packaging by Pharglass | ISO 11040-4 Compliant | For Insulin, GLP-1, Biologics & Self-Injection Systems
Pharglass pen injector cartridges are engineered to the highest pharmaceutical standards for use in insulin pens, GLP-1 agonist delivery systems (e.g., semaglutide, tirzepatide), and next-generation autoinjectors. Available in 1.8ml and 3ml capacities, these cartridges are manufactured from Type I neutral borosilicate glass, ensuring exceptional chemical resistance, low protein binding, and long-term stability for sensitive biologics and high-concentration formulations.
Fully compliant with ISO 11040-4—the global standard for prefillable glass cartridges—Pharglass cartridges feature precise dimensional tolerances, smooth inner surfaces, and consistent plunger glide force, enabling reliable dosing, reduced injection pain, and seamless compatibility with leading pen platforms from Ypsomed, Owen Mumford, Haselmeier, SHL Medical, and BD.
Whether you’re developing a branded self-injection therapy or a biosimilar, our cartridges deliver the performance, compliance, and scalability your drug-device combination requires.

Why Drug Developers Choose Pharglass Cartridges
In drug-device combination products, cartridge quality directly impacts patient experience and therapeutic efficacy. Poor glide force can cause dosing errors; surface defects can trigger protein aggregation.
Pharglass addresses these risks through:
- Tight tolerance control on outer diameter (OD), length, and tip concentricity
- Advanced washing and inspection to remove particles and fibers
- Validated stopper compatibility to prevent leaching or adhesion
- Full traceability and batch documentation for regulatory submissions (FDA, EMA, PMDA)
Our cartridges are used in commercialized diabetes therapies, obesity treatments, and clinical-stage biologics worldwide.
OEM & Integration Support
We partner with pharma and device companies to ensure seamless integration:
- Custom tip geometries for proprietary pen systems
- Coated plungers for high-viscosity drugs
- Laser marking for serialization or branding
- Regulatory support (DMF, technical dossiers)
Precision-engineered. Patient-tested. Globally trusted.
When your therapy depends on reliable self-administration, choose Pharglass pen cartridges—where pharmaceutical science meets device excellence.
