Disposable virus sampling tubes are suitable for late nucleic acid extraction and virus isolation of various virus samples such as influenza virus, avian influenza virus, coronavirus, hand, foot and mouth, measles, etc.
It is also suitable for the collection and transportation of specimens of Chlamydia, Mycoplasma, Mycoplasma solium, etc. Samples are usually collected from the oral cavity, pharynx, and nasopharynx of humans.
Disposable virus sampling tubes include sampling swabs and sampling tubes. Here we talk about the characteristics of sampling swabs and sampling tubes respectively.
Sampling swabs: Nylon flocked swabs are used (rayon is optional). Because nylon flocking has no toxic effect on microorganisms and viruses. It can collect and release virus samples and ensure the accuracy of polymerase chain reaction test results.
The flocked swab stem is made of ABS with a unique easy-break design that does not produce tiny debris during breakage. Easy to put into the sampling tube without being contaminated.
Sampling tube: polypropylene material, high temperature and high pressure (121C, 15 minutes) does not deform, low temperature (-196C) does not become brittle. Resistant to static extrusion and dynamic impact. Conical bottom design can resist centrifugation and vibration. Built-in transport medium (inactivates and maintains activity) for sample release and preservation to prevent leakage.
Sampling tubes have built-in magnetic beads for easy elution, facilitating the release of more virus into the sample preservation solution.
Our disposable virus sampling tubes are divided into two types, one inactivated and the other non-inactivated. Disposable virus sampling tubes have high practical safety and are mainly improved from nucleic acid extraction lysate to virus lysis preservation solution.
The sampling contains a high concentration of components that can effectively inactivate the virus, which can effectively prevent secondary infection of the operator, and also contains inhibitors that can protect the viral nucleic acid from degradation so that subsequent testing can be performed by NT-PCR. It can also be stored at room temperature for a relatively long period of time, saving the cost of storing and transporting virus samples.
Inactivated is mainly a virus maintenance solution preservation solution that is an improvement on the transport medium. It can maintain the activity of virus in vitro and the integrity of antigenic nucleic acid, protect the virus protein shell from decomposition, and maintain the originality of virus samples to a large extent.
This preservation solution can be used not only for nucleic acid extraction and detection, but also for virus culture, isolation and antigen detection. However, strict low temperature is required for long-term preservation after sampling.
Different disposable virus sampling tubes need to be selected for different testing purposes, and each of the two widely used disposable virus sampling tubes has its own characteristics. In order to meet the different testing requirements and different virus testing laboratory conditions, sampling of different disposable virus sampling tubes is essential.
However, it should be noted that whether inactivated or inactivated, disposable virus sampling tubes before sampling are strictly inactivated and disinfected to ensure that there are no other microorganisms in the tube, resulting in post-sampling virus decomposition or other effects leading to false detection. After swab sampling, if you use poor quality collection tools or preservation solution, it will affect the subsequent test results, or even cause false positives of misdiagnosis. Therefore, choose disposable virus sampling tubes produced by professional qualified manufacturers.
