Disposable virus sampling tube product qualification: Our products have passed the EU CE, U.S. FDA, ISO13485, China NMPA, SGS, TUV field certification, has the exclusive right to register trademarks and sales rights of products in many countries, in line with the "quality first, realistic and innovative, honest and law-abiding, win-win cooperation" quality policy Our products are exported to all over the world and have been unanimously approved by our customers.
The role of disposable virus sampling tube (use): disposable virus sampling tube is our best-selling star product, it is suitable for all kinds of influenza virus, avian influenza virus, coronavirus, hand, foot and mouth, rubella and other viral samples of nucleic acid extraction and late virus isolation. It is also suitable for specimen collection and transportation of Chlamydia, Mycoplasma, Mycoplasma solium, etc. Specimens are usually collected in the human mouth, throat, nasopharynx, anus, etc. Combined characteristics of our single-use virus sampling tube set: disposable virus sampling tubes include sampling swabs and sampling tubes, we separate the characteristics of sampling swabs and sampling tubes
①Sampling swab: our company uses nylon flocked swab (another rayon optional). Because nylon flock has no toxic effect on microorganisms and viruses, and does not contain RNA enzymes and DNA enzymes. It can maximize the collection and release of virus samples and ensure the accuracy of PCR test results.
Flocked swab rod is made of ABS, unique breakable design, no tiny debris generated during the breaking process. Easy to put into the sampling tube without being contaminated.
②Sampling tube: The tube body and cap are made of polypropylene, which will not deform at high temperature and pressure (121°C, 15min) and will not become brittle at low temperature (-196°C). Resistant to static extrusion and dynamic impact. Tapered bottom design resists centrifugation and shock. Contains transport media (inactivated and inactivated) for sample release and preservation, eliminating leakage.
The sampling tube has built-in magnetic beads to facilitate elution and release of more viruses into the sample preservation solution. Classification of single-use virus sampling tube: We have two types of liquid for single-use virus sampling tube, one is inactivated and the other is inactivated, where the inactivated virus sampling tube has higher operational safety. Sampling contains a high concentration of components that can efficiently inactivate the virus, which can effectively prevent the operator from secondary infection, but also contains inhibitors that can protect the virus nucleic acid from degradation, so that the subsequent detection by NT-PCR. It can be stored at room temperature for a relatively long period of time, saving the cost of virus sample storage and transportation. (Details can be found in the article - Disposable Virus Sampling Tubes ((Inactivated version))
The non-inactivated version can be mainly a virus maintenance fluid type preservation solution modified based on the transport medium. It can maintain the activity of virus in vitro and the integrity of antigen and nucleic acid, protect the virus protein shell is not easy to decompose, and maintain the originality of virus samples to a greater extent. In addition to nucleic acid extraction assays, this preservation solution can also be used for virus culture, isolation and antigen detection, etc. However, prolonged storage after sampling requires maintaining strict low temperature.
For different testing purposes, different virus sampling tubes need to be selected, and each of the two types of virus sampling tubes currently in widespread use has its own characteristics. In order to meet the different testing requirements, as well as different virus testing laboratory conditions, sampling different virus sampling tube is very necessary. But it should be noted that: whether inactivated or non-inactivated, the virus sampling tube before sampling must be strictly inactivated sterilization to ensure that there are no other microorganisms in the tube, resulting in sampling after the virus decomposition or other effects caused by false detection. Swab sampling, if the use of quality lack of collection tools or preservation solution, will affect the subsequent test results or even cause false positives of misdiagnosis, so be sure to choose the virus sampling tube with professional qualification manufacturers.
Ltd. as a medical supplies and R & D medical equipment manufacturer with many years of experience, has a perfect quality control system and 10,000-grade standard clean workshop to ensure the professional production of high-quality virus sampling tubes, Huarikang is committed to creating a product peace of mind, process reassurance, customer happiness a series of product services, Huarikang worth your trust.
