Screw syringe
Spiral syringe with medical-grade PP/PC, precise dosing (0.01ml), ISO 11040, CE, FDA certified—ideal for biologics, aesthetic fillers, and global B2B/B2C healthcare markets.
Our spiral syringe is designed to deliver unparalleled precision, safety, and versatility in drug administration across various medical fields including aesthetics, ophthalmology, dentistry, and biological therapies. Engineered from a blend of medical-grade polypropylene (PP) and polycarbonate (PC), it ensures strong chemical stability, preventing any interaction with vaccines, biologics, or aesthetic fillers, thus maintaining drug purity.
Certified to ISO 11040, USP Class VI, and holding CE and FDA approvals, our syringes are globally compliant, making them ideal for cross-border B2B and B2C sales. They are free from harmful substances like BPA, phthalates, and heavy metals, ensuring low extractables suitable for sensitive drugs and long-term use. With excellent biocompatibility (cytotoxicity ≤ Grade 1), they minimize the risk of adverse reactions.
The spiral design offers superior sealing performance compared to traditional syringes, providing 100% leak-proof and anti-backflow capabilities. This ensures accurate dosing down to 0.01 mL, critical for applications such as aesthetic fillers and ophthalmic injections. The spiral locking mechanism prevents accidental plunger slippage during injection, enhancing operational safety. A uniform glide force of ≤12 N ensures smooth operation, reducing user fatigue.
Available in 0.3 mL to 5 mL capacities, with graduations as fine as 0.01 mL, these syringes cater to a wide range of therapeutic needs. Needle options span from 25G to 32G, with ultra-fine gauges minimizing pain for sensitive areas. The ≥92% transparency allows clear visualization of medication clarity, ensuring safe administration.
Packaged in individual sterile blisters with needle caps, plus the spiral seal, these syringes offer triple protection against contamination, leakage, and needlestick injuries. Their impact resistance exceeds glass by over 4 times, with only ⅓ the weight, facilitating easier transportation and lowering logistics costs. Stable from –20°C to 45°C, they have a shelf life of 24-36 months, making them suitable for diverse environments.
Designed for aesthetic clinics, specialized hospitals, dental practices, and laboratories, these syringes can be customized with brand logos, multilingual instructions, and colored graduations, meeting the needs of different markets worldwide. Offering superior cost-efficiency compared to glass alternatives, they are perfect for bulk procurement and global distribution.
