How to Choose a Cost-Effective Virus Transport Medium: A Full Guide from Specs to Brand and After-Sales

Are you caught in the procurement dilemma every quarter?
Pick the cheapest tubes and you soon pay again—leaks, contamination, repeat tests.
Pick a premium brand and you blow the budget on features you never use.

Real cost-effectiveness is not “the lowest price”; it is the smartest balance of QUALITY, FIT and SERVICE.
Huachenyang has produced virus transport media (VTM) for over a decade under the rule “right quality, right price, right support”.
Below is the playbook we give to hospitals, labs and distributors who want maximum value for every cent.

1. Pick the RIGHT SPEC – don’t pay for what you don’t need
   Key parameters decoded

• Tube volume
  ‑ 3 mL – ideal for daily screening; less dead volume, lower freight.
  ‑ 5 mL – only when storage >48 h or sputum is expected.
• Medium type
  ‑ PCR grade – guanidine-based, stabilises RNA 72 h at 4 °C.
  ‑ Culture grade – protein-rich, keeps virus alive for isolation.
  Using the wrong type is the #1 cause of invalid results.
• Seal level
  ‑ Single seal (plug) – outpatient clinics, same-day testing.
  ‑ Double seal (plug + screw cap) – long haul, altitude changes.
• Sterility
  ‑ 10⁻⁶ SAL is the medical standard; anything less risks cross-contamination.

Huachenyang portfolio
3 mL or 5 mL, PCR or culture medium, single or double seal—mix and match so you never buy unnecessary performance.
