USP Type I Glass Cartridges for Pen Injector Systems

LINUO manufactures neutral borosilicate glass cartridges made from USP Type I pharmaceutical glass, designed for disposable and reusable pen injector systems. With high dimensional accuracy, stable mouth geometry and optimized inner-wall siliconization, our glass cartridges support smooth gliding force, precise micro-dosing and reliable drug delivery performance.

Available in 1.5ml, 1.8ml and 3ml standard formats, as well as specialty dual-chamber and RTU sterile cartridge solutions, LINUO glass cartridges are widely used for insulin, GLP-1, dental local anesthesia, peptides, biologics and high-value injectable formulations. Each cartridge is produced in a GMP smart manufacturing environment with thermal laser-cutting, 100% online inspection and full compliance support including FDA DMF, ISO 15378, EU CEP and CNAS-accredited testing.

Why Pharmaceutical Manufacturers Choose Linuo Cartridges

100% Pen Injector Compatibility

Engineered to fit universal disposable and reusable pen injector systems, LINUO glass cartridges support stable assembly, smooth operation and reliable drug delivery performance across insulin, GLP-1 and dental applications.
Stable Gliding Force Control

Optimized baked-on siliconization forms a smooth inner surface that helps prevent “stuttering” in electronic and spring-loaded pens, ensuring consistent gliding force and accurate micro-dosing.
Zero-Debris Thermal Laser-Cut Body

Advanced thermal laser-cutting reduces the risk of glass micro-flakes, jagged edges and inner debris. This helps protect sensitive formulations from delamination, contamination and pH shifts.
Precision Mouth & Leak-Proof Seal

ISO 11040-4 compatible mouth geometry supports stable crimping, reliable sealing and strong compatibility with plungers, caps and pen injector assembly systems.
RTU Sterile Format Available

RTU cartridges are pre-washed, depyrogenated and sterilized, then delivered in Nest & Tub packaging for direct-to-line aseptic filling. This reduces in-house preparation steps and supports high-end injectable production.
Laser Coding & Batch Traceability

High-precision graduation scale printing, HD silk-screen decoration and laser coding options support clear dosage visibility, product identification and full batch traceability.
