1) Disposable Sterile flocking nylon swab or polyester fiber swab, one piece.
2) 1-6m UTM liquid(Higher positive rate of PCR test), Two glass beads. sealed collection tube, one piece .
3) Biosafety bag, one piece.
4) The swab and collection tube is packed by paper-plastic bag or blister bag, Sterilized by Gamma radiation.
5) 2 years expiry at normal temperature.

1. Sample collection tube:
Tube body and cap are made by Polypropylene, No deformation after HTHP(121°C, 15min), no embrittlement under low temperature (-196°C). it can bear static extrusion and dynamic impact. Taper bottom design makes it bear centrifugation and shaking. Leakage proof.

2.Sample storage liquid（Classic Medium / Inactivated Medium）:
Classic：According to vast test of the influence to cells among Basic liquid, buffer system, protein stabilizer, freezing protective agent, amino acid,etc. We summarize a formula which is most applicable for the virus storage. It can keep a high efficiency for virus storage, and largely increase the positive rate of virus culture. Glass bead inside for easy elution, it can make more microorganism such as virus release to the storage media.

Inactivated： The tube contains l -2ml of preservation medium, This products include virus lysates and nucleic acid preservation solutions, and mixing it with virus samples to inactivated virus and maintain the integrity of virus nucleic acids at room temperature for 7 days. The collected viral RNA samples can be widely used in gene detection, such as PCR and high-throughput sequencing.

3. Flocked swab:
Innovative jet embedded nylon technology can improve the efficiency of the sample collection from the patient at the largest degree.The nylon is adhered vertically and uniformly on the surface of swab tip, which can improve the efficiency of collecting and releasing cells and liquid samples. Improve analytical sensitivity, No specimen residual and can accelerate the specimen treatment. PS sticker is easy to break off. Adapted to cervix uteri, nasopharynx, oral cavity, Forensic Acquisition System and DNA collecting etc.
