From collection to laboratory analysis, the virus transport medium (VTM) tube determines whether the final result can be trusted. Huachenyang VTM triple-lock design cuts RNA degradation risk by 90 %, buying precious time for early infectious-disease screening.

What is a VTM tube—and why is it an “invisible shield”?
It is far more than a plastic tube. Each Huachenyang VTM is a pre-filled, 2–3 mL “safe box” of viral transport medium. Its buffered system keeps nucleic acids intact for 48 h at 4 °C, ensuring accurate downstream PCR, antigen or sequencing assays. Medical-grade, low-adsorption polypropylene limits sample loss to < 1 %—five times better than the industry average of 5 %.

Huachenyang’s three core technologies

1. Patented buffer: viral-stabilising factors plus broad-spectrum antibiotics maintain Ct drift ≤ 0.5 after 72 h at 4 °C.
2. Negative-splash cap: forms –0.03 MPa when closed, leak-free for 96 h, IATA 6.2 certified for air freight without secondary packaging.
3. Colour-coded system: red for NP, blue for OP, yellow for sputum—boosting nurse sorting speed by 40 % and cutting pooling errors.

Real-world case: 100 000 tubes delivered in 7 days
When an imported mpox case was detected at a major port in 2024, customs needed 100 000 tubes within a week. Huachenyang’s GMP-automated filling lines (daily capacity 500 000 pcs) and FDA-EUA green lane delivered the order in 5 days; extraction success rate reached 99.2 %, allowing contact tracing to be completed in 48 h.

How to choose the right VTM tube?
Check certificates: CE, FDA, ISO 13485—all three are essential.
Check formulation: does it combine guanidine inactivation with nucleic-acid stabilisers?
Check supply chain: can 48-h emergency delivery be guaranteed?

Huachenyang offers 5 mL, 10 mL and 15 mL formats for NP, OP, sputum or environmental samples, with OEM branding and multi-language labelling—one-stop export solution.
