• Product Description: Cell-Free DNA (cfDNA) Collection and Preservation System by Orsin Medical Technology

  • 1. Product Description

    ---

  • Orsin Medical Technology revolutionizes liquid biopsy with our next-generation cfDNA Blood Collection Tube, engineered to deliver uncompromised sample quality for precision diagnostics and research.

    Why Choose Orsin’s cfDNA Tube?

  • Ultra-Stable Preservation – Proprietary formula inhibits hemolysis and nucleases, maintaining cfDNA integrity for extended periods.

  • Clinical-Grade Reliability – Validated for NIPT, oncology, and transplant monitoring, ensuring consistency across applications.

  • Seamless Workflow Integration – Compatible with automated extraction platforms and major downstream assays (qPCR, NGS, ddPCR).

  • Innovation in Every Tube:
    Our barrier-coated interior prevents gDNA contamination, while the vacuum-sealed design ensures leak-proof safety during transit.

    Ideal for:
    ✔ Early cancer detection
    ✔ Fetal genetic screening
    ✔ Minimal residual disease (MRD) monitoring
    ✔ Pathogen DNA analysis

  • Global Compliance – Manufactured under ISO 13485 standards for guaranteed performance.
