1. Sample collection
   Used to collect secretions containing viruses (such as throat swabs, nasal swabs, sputum, etc.), usually used with sterile swabs.

Suitable for sampling respiratory viruses (such as influenza, new coronavirus), enterovirus, etc.

2. Sample preservation and transportation
   Preservation fluid composition: The tube contains a specific liquid (such as virus maintenance fluid, Hank’s fluid or inactivated preservation fluid), which can:

Maintain virus activity (for subsequent culture or nucleic acid testing).

Or directly inactivate the virus (reduce infectivity, suitable for rapid testing).

Stabilize nucleic acids: Prevent sample degradation and ensure the accuracy of PCR and other test results.

Anti-leak design: The sealed tube cap avoids leakage during transportation and meets biosafety standards.

3. Prevent cross-contamination
   Disposable materials: Avoid contamination between samples caused by repeated use.

Aseptic processing: Sterilize before leaving the factory to ensure that no other microorganisms interfere with the test.

4. Standardization and traceability
   Labels and barcodes facilitate sample numbering, record patient information, and ensure traceability.

Comply with laboratory and CDC specifications.

5. Biosafety protection
   Reduce the risk of direct exposure of medical staff to viruses, especially for highly contagious pathogens (such as new coronavirus, Ebola virus, etc.).

Common application scenarios
Virus detection in hospitals and CDCs (such as COVID-19, influenza A).

Epidemiological surveys, large-scale screening.

Sample collection in scientific research or vaccine development.
