Virus Transport Medium Tube with Swab:

Note:5 ml / 10 ml sample tube(optional)

        Pharyngeal/nasal swab/Pharyngeal+nasal swab(optional)

        Cell preservation solution A (non-inactivated)

        Cell preservation solution B (inactivated)

*Cell preservation solution B: The virus in the sample is lysed and inactivated, but its nucleic acid is kept stable (inactivated type). It is mainly used for nucleic acid detection. The main components are equilibrium salt, lysis reagent, stabilizer, phenol red solution, etc.

Virus Transport Medium Tube with Swab

*Safe and reliable

*CE and FDA certificate

*The antibiotics in Hanks can prevent bacterial and fungal contamination effectively

*The transparent preservation liquid can inactivate virus efficiently and help reduce the degradation of viral nucleic acid

Virus Transport Medium Tube with Swab

1.Advantage:

*High safety: medical materials, good sealing, good stability, prevent leakage, ensure biosafety;

*options: nose/throat swab + inactivated/non-inactivated preservation solution, randomly selected to meet different experimental requirements;

*Inactivated high efficiency: high quality formula can inactivate virus quickly and efficiently and avoid aerosol infection risk

*Stable nucleic acid: the preservation solution contains special stable components to ensure the

stability and integrity of virus nucleic acid in vitro preservation and transportation (anti-degradation);

*Easy to operate: single and double swab optional, no refrigeration, room temperature transportation.

2. Fully automated production process in a sterile environment:

*10000-12000 units/hour;

*The integrated process of feeding, filling, capping and labeling;

3.Unique flocking swab:

Advantage:

*Suitable for oral and nasal virus and DNA sampling;

*Flocking materials, to ensure a high sampling rate, sample release integrity, fast;

*It is non-toxic to cells and viruses and does not contain RNA enzyme, which enhances the sensitivity of diagnosis.

*15cm lengthening treatment, 8cm/3cm can be broken design, convenient sampling, avoid the risk of pollution;

*Single aseptic packaging for easy handling and transportation.

4.Operation process:

Step 1:According to the sampling requirements and for different test purposes, swabs were used for sampling.

Step 2:Place the swab after sample collection into the sample tube of the cell preservation solution.

Step 3:Break the swab at the vulnerable cutting point of the swab rod and discard the tail.

Step 4:Tighten the cover of the storage liquid tube.

Step 5:Mark information as required on the label of the storage liquid tube.

Sample storage: Freshly collected samples can be transported to the laboratory as soon as possible under the condition of normal temperature (5-30℃). The effect of ice packs is better during transportation. Samples tested within 48 hours can be stored at 2-8℃.Samples that cannot be tested within 48 hours should be stored at -70℃ or below, and the samples should be tested within a week to avoid repeated freeze-thaw cycles.

5.Clinical promotion:

All parts of the country responded positively. At present, the main screening population includes:

Persons who have fever, cough or have been in contact with patients with fever and cough;

1.Patients and caregivers about to undergo surgery;

2.Persons requiring nucleic acid tests for admission;

3.Persons returning from high-risk areas;

4.The resumption of work units have accounting requirements for employees, etc.

б. The number of nucleic acid tests is huge:

*At present, Hubei Province, Beijing, the Three northeastern provinces and Guangdong province have taken the lead in responding, and are conducting nationwide nucleic acid testing under the auspices of the government.

*Since Wuhan started centralized nucleic acid testing on May 15, more than 9 million samples and 6.5 million tests have been completed on May 24.0n April 13, WeChat self-help novel coronavirus nucleic acid test service will be launched in Guangzhou. On April 18, it will be upgraded to the normal service on weekends and holidays. On May 7,the WeChat self-help novel coronavirus nucleic acid test service will be launched again.

*Novel Coronavirus nucleic acid detection service has been set up online and offline in Henan, Beijing and Guangdong.

*Hunan has included viral nucleic acid and antibody testing in medical insurance fees, and encourages and supports nucleic acid testing for the whole population.

Virus Transport Medium Tube with Swab:

Covid-19 selected the right VTM

*Sample collection and preservation is the first step in detection,

*"Garbage in, Garbage out,"

*the correct virus preservation solution makes COVID-19 detection twice as effective!

*Without guanidine, the "false negative" was reduced. On the 7th day, the nucleic acid of the guanidine preservation solution was less than 20%, and the RNA was rapidly degraded in the preservation solution!

*It is a more ideal choice to inactivate the virus while collecting the samples, which is safe and efficient.

*The storage volume in the sampling tube should be appropriate

2ml : Single person collection , the virus concentration is 1.5 times !

3ml: In case of initial screening and mixing, 3-5 persons are put into the same sampling tube.

*Room temperature:

RNA instability, our storage solution can store virus nucleic acid stably at room temperature, solve the problem of sample transportation, and improve the accuracy of detection.

*High temperature resistant virus preservation solution:

high temperature inactivation (treated above 56'C for 30min) will lead to the degradation of viral nucleic acid and reduce the detection rate.Affinity virus preservation solution unique nucleic acid stabilizer, high temperature inactivation has no significant effect on the nucleic acid integrity of coronavirus.

*For nasal and pharyngeal swab sampling, it is recommended to use inactivated virus, suitable for liquid storage, transportation at room temperature, and protect the virus from high temperature inactivation treatment!
