Non inactivated type: the prepared water is purified by multiple membranes, EDI purification, distillation and multiple membrane filtration. The full name is no human contact, which can ensure that the water has high purity and does not contain RNase and bacterial endotoxin. Better store samples to ensure that they will not be degraded during transportation, and maintain the original properties to the greatest extent.

Inactivation: instantly inactivate respiratory pathogens; It can be stored and transported innocuously at room temperature; Protective agents prevent nucleic acid from being degraded; After nucleic acid extraction, it is suitable for downstream detection.

[storage]

Non inactivated: it can be stored at 2-35 ℃ for 12 months. After sampling, it shall be transported to the laboratory within 48 hours under 2-8 ℃ or stored under - 70 ℃.

Inactivated: it can be stored at 2-35 ℃ for 12 months.

After use, the sample can be stored at room temperature for 1 week. If it needs to be stored for a longer time, please put it at - 80 ℃.

[shelf life] one year

[usage]

1. Before sampling, clean your hands, tear off the outer package of the sampling swab and take out the swab. Be careful not to touch the swab head.

2. According to different sampling requirements, use a swab to sample at the corresponding parts.

3. After sampling, quickly put the swab into the sampling tube with preservation solution to avoid contacting other parts.

4. Break the swab rod, discard the tail, and then tighten the pipe cover to complete the sampling.

5. Properly place and store the virus sampling tube after sampling, and transport it to the testing department for testing within 1 week.

6. Specific sampling methods mainly include the following:

Pharyngeal swab: pass the swab over the root of the tongue and wipe bilateral pharyngeal tonsils and posterior pharyngeal wall.

Nasal swab: gently insert the swab into the nasopharynx in the nasal tract, stay for a moment, and then slowly rotate and exit.
