RTU Glass Cartridge Advantages

Plug-and-Play Efficiency & Extreme Cost Savings

RTU sterile cartridges help bypass in-house washing, siliconization, depyrogenation, and sterilization preparation before filling. This supports faster production setup and simplified integration into sterile filling workflows.

Zero Downtime direct-to-filling

Our standardized Tub formats perfectly match mainstream automated filling machinery without any manual adjustment, ensuring a seamless, high-speed transition to your production line.

Reduced Contamination Risk

Tyvek® double breathing bags, clean-peel packaging, WFI rinsing, and controlled sterile barrier handling help reduce environmental bioburden and particle introduction risks.

Zero Breakage Risk During Transportation

Independent cavity suspension design prevents cartridge collision during transportation and decrating, helping reduce breakage risks during handling.

Smart ETO Sterilization & Tier-1 Quality

Features an extreme multi-stage washing program and rigorous ETO terminal sterilization (with >3KPa/min pre-vacuum leak alerts). Backed by global leaders like SCHOTT, West, and DuPont.

Innovative Dual-Chamber & Standard Options

Offering standard sizes (1ml–3ml) for high dosing accuracy, and premium Dual-Chamber models (3ml–5ml) specifically engineered for “Powder + Solvent” combinations, perfectly simplifying the reconstitution process.

Zero Downtime direct-to-filling

Our standardized Tub formats perfectly match mainstream automated filling machinery without any manual adjustment, ensuring a seamless, high-speed transition to your production line.
