Key Advantages
● 3 ML Barrel With 13 MM Neck Geometry
The published standard configuration uses a 3 mL cartridge and a 13 mm neck. Controlled barrel, shoulder and neck geometry keeps the cartridge seated and the piston aligned with the stopper in pen mechanisms that use small dose increments.
● Type I Glass With Bromobutyl Rubber Stopper
The standard material set combines Type I glass with a bromobutyl rubber stopper. This glass-and-elastomer interface provides a defined container format for the drug compatibility and closure program during storage and delivery.
● Siliconized Stopper Movement And Five-Year Shelf Life
The published configuration uses a siliconized stopper and lists a five-year shelf life. Siliconization controls break-loose and glide behavior as the stopper moves within the approved cartridge specification.




Customization Options
Cartridge design starts with the target fill volume and injector interface. The barrel, shoulder, neck and internal geometry are treated as one dimensional system. Type I glass or an approved polymer can then be paired with a matched plunger, septum and seal for the intended filling and device-use conditions.
Further customization depends on the agreed supply state. Siliconization, washing, sterilization and packaging presentation are set as one processing route for either bulk supply or an approved ready-to-use format.


Customization Process
Container Requirements
Drug-contact, fill-finish and device-interface inputs are approved as one cartridge specification before component selection.
Component And Drawing Selection
Barrel and closure geometry are matched as a system. Tolerances and quality limits are then fixed for sample production.
Sample Assembly
Cartridge samples are assembled in the intended supply state so device fit, plunger movement and closure seating can be checked together.
System Testing
Verification covers dimensional fit, seal performance and stopper movement with the agreed container configuration.
Pilot Supply
A pilot lot confirms the processing route, component assembly and packaging presentation under production conditions.
Lot Release
Final inspection and traceability review are completed against the approved container specification before shipment.
Quality Control
Inspection covers the barrel, shoulder and 13 mm neck geometry that governs device seating and stopper travel. Visible glass and closure defects are screened before packing; 100% inspection is used only when stated in the control plan. The assembled closure system is evaluated for seal performance and stopper movement. ISO 11608-3 or ISO 13926-1 is referenced only when the applicable edition is included in the agreed verification scope. Cleanliness, sterilization and packaging-integrity controls follow the approved supply state, and material and component records remain traceable to each released batch.
FAQ
Q1: Can a reference cartridge sample be provided before production?
A1: A basic reference sample can be supplied when available. Project-specific samples require confirmed barrel, neck, stopper and seal specifications before sample assembly.
Q2: What is the MOQ?
A2: The standard MOQ is based on a full production and packing lot. The exact quantity depends on cartridge size, material, closure components and the selected sterile or non-sterile supply state.
Q3: Does a 3 mL cartridge fit every pen injector?
A3: No. Capacity alone does not confirm compatibility. Barrel diameter, shoulder position, neck geometry, stopper position and piston contact must be checked against the target device drawing and physical sample.
Q4: Can the cartridge be supplied empty for pharmaceutical filling?
A4: Yes. The cartridge can be supplied as an empty container assembly for the customer's filling process. Drug filling and final combination-product release are outside the standard cartridge supply scope unless separately agreed.
