The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict. The virus sampling tubes must meet the requirements of three aspects at the same time:

1. The safety of transportation.
Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations.

2. The safety of preservation.
Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations.

3. The validity of the sample.
Ensure that the sampling tube itself will not have a toxic effect on the sample.
