2.25ml 27G 1/2

Our 2.25 mL pre-filled syringe is a next-generation drug delivery solution engineered for safety, precision, and global compliance. It bridges a critical market gap between standard 1 mL and 3 mL formats, offering optimal dosing for medium-volume therapeutics while excelling in five core dimensions: material integrity, ergonomic performance, long-term stability, manufacturing excellence, and multi-scenario adaptability.

Material Safety & Global Regulatory Compliance:
Constructed from medical-grade high-borosilicate glass, it delivers exceptional chemical inertness—ensuring zero interaction with vaccines, biologics, hormones, antibiotics, and even lipid-soluble formulations. Fully compliant with ISO 11040, USP/NF, EP, and JP pharmacopeial standards, and certified under CE, FDA, and GMP, it enables seamless market access worldwide. Free from BPA, phthalates, and heavy metals, it meets stringent requirements for pediatric and high-sensitivity drugs. The ultra-smooth inner surface achieves protein adsorption <0.08%, minimizing drug loss and preserving potency. Validated for 121°C steam sterilization with a sterility assurance level (SAL) of 10⁻⁶, it satisfies the most rigorous aseptic packaging demands.

Precision Engineering & Clinical Usability:
The 2.25 mL capacity uniquely addresses mid-dose applications—such as certain vaccines, aesthetic dermal fillers, and antibiotic regimens—eliminating under-dosing or wasteful overfilling. A 27G × ½” (12.7 mm) ultra-fine needle ensures low-pain injection (≤3/10 on pain scale), ideal for children and sensitive patients. Optimized for subcutaneous and intramuscular routes, it offers high procedural tolerance. The pre-filled, ready-to-use design reduces clinical prep time by over 60%. With ≥92% light transmittance, the barrel allows clear visual inspection for particulates or discoloration. Needle sharpness meets top-tier industry standards with puncture force <8 N, while plunger glide force is uniformly controlled at ≤12 N to prevent dosing errors. Uniform wall thickness (tolerance ≤0.08 mm) ensures comfortable grip and precise single-handed control.

Sealing Integrity & Storage Robustness:
A triple-seal system—medical-grade butyl rubber plunger + aluminum crimp + PP tip cap—provides comprehensive protection against leakage, microbial ingress, oxidation, and evaporation, supporting a shelf life of 24–36 months. The glass barrier achieves an ultra-low oxygen transmission rate of <0.008 cc/(pkg·day·atm). Dose accuracy is maintained within ±1.5%. Stable across –25°C to +65°C, it withstands extreme shipping conditions with a breakage rate <0.1%. The medical-grade PP needle cap ensures sterility and prevents needlestick injuries during handling.

Quality Assurance & Traceability:
Needle-barrel bond strength exceeds 60 N, eliminating detachment risk. Manufactured in a Class 10,000 (ISO 7) cleanroom with microbial load ≤5 CFU/unit—surpassing industry norms. Every batch undergoes 12 rigorous QC tests, including leak integrity, sharpness, clarity, and seal validation, achieving 100% pass rate. Needles are precision-polished and passivated to minimize tissue trauma. Butyl rubber plungers are extractable-free and odorless, ensuring broad drug compatibility. Full digital traceability enables real-time access to batch number, production date, and full QC reports.

Market Differentiation & Versatility:
Perfect for vaccination programs, insulin therapy, aesthetic medicine, hospital treatments, and lab research. The 2.25 mL volume fills a strategic niche, offering clear differentiation from competitors. Compact (≤9 cm length) and lightweight (≤12 g/unit), it reduces logistics costs. Customizable printing (brand, drug name, expiry, batch) enhances recognition and premium positioning. As a closed-system pre-filled device, it minimizes contamination risk—making it indispensable for public health initiatives and high-value biologic delivery.
