Sterile Prefillable Cartridges – 1.5ml, 1.8ml, 3ml, 4ml Type I Glass | ISO 13485 & EP 3.2.1 Compliant
Ready-to-Fill Primary Packaging by Pharglass for Autoinjectors, Pens & Wearable Injectors
Pharglass sterile prefillable cartridges are precision-engineered for next-generation self-injection therapies, including GLP-1 agonists (e.g., semaglutide, tirzepatide), insulin, monoclonal antibodies, and high-viscosity biologics. Available in 1.5ml, 1.8ml, 3ml, and 4ml capacities, these cartridges are made from Type I neutral borosilicate glass and fully comply with فصل ۳.۲.۱, USP, and ISO 13485 quality standards—ensuring the highest level of chemical inertness, dimensional accuracy, and patient safety.
Each cartridge is gamma or ETO sterilized to SAL 10⁻⁶, pre-assembled with a medical-grade bromobutyl plunger, and packaged in nest trays within double sterile pouches, making them true ready-to-fill (RTF) components. This eliminates in-house cleaning, depyrogenation, and sterilization—reducing contamination risk, operational costs, and time-to-market for drug-device combination products.
Designed for seamless integration with leading autoinjector and pen platforms (including Ypsomed, Owen Mumford, Haselmeier, and SHL Medical), Pharglass cartridges deliver consistent glide force, low protein binding, and reliable dosing performance.

Why Global Pharma Trusts Pharglass RTF Cartridges
In the era of high-value injectables, container quality directly impacts drug stability, patient comfort, and regulatory approval. Pharglass addresses critical challenges:
- Protein aggregation? → Ultra-smooth glass surface + low silicone migration
- Dosing inconsistency? → Tight tolerance on OD, length, and tip concentricity
- Supply chain delays? → Dedicated RTF production lines with scalable capacity
Our facility operates under ISO 13485 with full documentation support—including Certificates of Analysis (CoA), sterilization validation reports, and Drug Master File (DMF) assistance for FDA/EMA submissions.
Customization & Partnership
We support your unique drug-device needs with:
- Custom tip geometries (Luer lock, staked needle interface, etc.)
- Plunger coating optimization for viscous drugs
- Laser etching or barcoding for serialization
- Regulatory dossier collaboration
From molecule to patient—delivered with precision.
Pharglass sterile prefillable cartridges empower innovators to bring life-changing injectable therapies to market faster, safer, and more reliably.
