Injection-Molded Medical Test Tubes: Precision & Sterile Solutions
Introduction
As a leading manufacturer of medical-grade injection-molded products, we specialize in high-precision test tubes engineered for clinical diagnostics, laboratory research, and point-of-care testing (POCT). Our injection molding process ensures exceptional dimensional consistency, uniform wall thickness, and reliable performance—all compliant with global medical standards. Designed for safety, efficiency, and scalability, our test tubes meet the rigorous demands of healthcare facilities, research labs, and diagnostic device manufacturers worldwide.
Core Product Highlights
1. Precision Injection Molding Technology
✅ Dimensional Consistency: Molded with CNC-machined cavities (tolerance ±0.02mm) for uniform outer diameter (OD) and length, ensuring compatibility with test tube racks, centrifuges, and automated analyzers.
✅ Uniform Wall Thickness: 0.8-1.2mm wall thickness (controlled via advanced injection molding parameters) for optimal pressure resistance and stable centrifugation (up to 15,000rpm).
✅ Smooth Surface Finish: Flash-free design (Ra ≤0.05μm) to prevent sample adhesion and ensure easy pipetting/cleaning (critical for clinical accuracy).
✅ High-Speed Production: Automated injection molding lines with output capacity of 1M+ units/month, supporting bulk orders with consistent quality.
2. Medical-Grade Material & Sterility
✅ Premium Injection-Molded Plastics:
PP (Polypropylene): FDA 21CFR §177.1520 compliant, heat-resistant (121℃ autoclaving), chemical-resistant (alcohols, acids, bases), and biocompatible (ISO 10993 certified).
PET (Polyethylene Terephthalate): High transparency (light transmittance ≥90%), rigid structure, and excellent barrier properties (ideal for sensitive sample storage).
✅ Sterile Assurance: Gamma-irradiated (ISO 11137) to Sterility Assurance Level (SAL) ≥10⁻⁶, with sterile packaging (individual/racked) to prevent cross-contamination.
✅ Non-Toxic & Leach-Resistant: No heavy metals or harmful additives, ensuring sample integrity for diagnostic testing.

4. Compliance & Quality Assurance
Global Certifications: ISO 13485 (Quality Management System), FDA 21CFR §177, CE Marking (MDR 2017/745), USP Class VI, ISO 10993 (Biocompatibility).
Rigorous Quality Control:
Incoming inspection: Material certification (MTR) verification.
In-process monitoring: Real-time tracking of injection pressure, temperature, and cycle time.
Final testing: Dimensional inspection (CMM), sterility sampling, and leak-proof testing.
Full Traceability: Batch numbering system covering raw materials, production parameters, and sterilization details for regulatory compliance.
Applications
✅ Clinical Diagnostics: Blood chemistry, hematology, microbiology, and immunology testing in hospitals, clinics, and diagnostic labs.
✅ Research & Development: Cell culture, molecular biology, forensic analysis, and pharmaceutical research.
✅ Point-of-Care Testing (POCT): Disposable test tubes for rapid diagnostic kits (e.g., glucose, cholesterol, COVID-19 antigen testing).
✅ Veterinary Medicine: Animal sample collection and analysis for livestock, pets, and wildlife research.
✅ Industrial Testing: Environmental sample (water, soil) analysis, food safety testing, and chemical reagent storage.
