VST-01

non-inactivated virus sampling tube thickened and anti-leakage design,complies with WHO regulations and biosafety regulations.

【Product name】
Single-use virus sampling tube (non-inactivated), also called DNA Virus Sampling Tube, or Viral Transport Medium Test Tube.

【Usage】
Used for sample collection, transportation and storage, etc.

【Principle of Inspection】
The osmotic pressure maintaining agent contained in the preservation solution maintains the isotonic environment, protects the cells, and further protects the viruses living in the cells. The contained pH buffering agent ensures that the internal environment of the preservation solution is not affected by internal and external factors and causes severe pH fluctuations within a certain range, and provides a stable and suitable pH external environment for the virus in the preservation solution. The contained stabilizer can increase the survival time and infectivity of the virus in the preservation solution when the virus exists independently, and the inhibitor can inhibit the viability of non-viral microorganisms such as bacteria in the sample, so as to ensure that the viability of the virus in the sample is basically free from contamination of the adverse effects of bacteria. The contained nutrients provide the basic nitrogen source, carbon source or other nutritional factors necessary for the survival of the virus or parasitic cells. The nutritional vitality necessary to maintain the virus or parasitic cells is impaired, which is also to maintain the viability of the virus in the sample. need. The indicator contained in the preservation solution can be an acid-base indicator, and the pH value of the discolored area is 6.8 (yellow) to 8.0 (purple).

【Main composition】
This Non-inactivated Virus Sampling Tube is composed of sampling tube, swab, preservation solution, etc.

[Storage conditions and validity period]
Storage conditions: room temperature, protected from light
Validity period: 12 months
Note: After the sample is built in the sampling tube, it generally needs to be stored and transported at 2-8°C.
