Flocked Tip Swab| China Flocked Swab Factory and Manufacturers.
Detection of viral nucleic acid sequence based on reverse transcription polymerase chain reaction (RT-PCR) is the main means for large-scale screening of new coronary pneumonia.
Generally, nucleic acid detection technology has the characteristics of early diagnosis, high sensitivity and specificity.
And it has the advantages of sample collection and preservation, personnel operation, nucleic acid extraction.
The performance of the kit is the cause of false negative or false positive test results.
Flocked swabs are the main samples for PCR. In the selection of raw materials, flocked glue plays a key role in the collection and release efficiency of swabs. Whether to use high-quality aqueous flocking glue is the main factor affecting the water absorption and hydrophilicity of fluff. The experiment is to compare the sample collection effects of swabs flocked with different glues.
What is a flocked tip swab？
The top of the flocking swab is a nylon fiber structure.
Nylon fibers are deposited on the surface of plastic rod in a certain direction by electrostatic field to form brush layer.
The layers are completely parallel and perpendicular to the inner rod surface.
Flocked tip swab brush head can effectively collect samples.
Flocked tip swab factory Product advantages.
The flocked swab can completely capture the cell sample through the directional friction effect of the brush fiber layer.
The capillary movement between the nylon fibers at the front end of the flocking swab can form a strong hydraulic pressure for absorbing liquid or cell line samples.
Cell samples can also be evenly and neatly concentrated on the near surface of brush fibers, so more than 95% of the samples can be released finally.
How are a flocked swabs used for specimen collection?
Flocked Tip Swab- swab manufacturer
1. Disposable sampling swabs for oral cavity and nasopharynx.
Collect human respiratory tract samples. The function of nylon staple fiber is like a soft brush, which can effectively improve the collection of cell materials; The capillary movement between fibers forms a strong hydraulic pressure, so as to absorb the liquid sample; At the same time, the sample is close to the swab surface and easy to elute.
2. Gynecological sampling swab.
Enough cervical epithelial exfoliated cells were collected for human papillomavirus (HPV) nucleic acid detection and other detection methods. So as to assist the clinical to judge the disease risk and type of the subject.
3. Virus and bacteria sampling.
Nylon flocking swab has good collection and transportation effect on virus and bacteria.
4. Disposable DNA sampling.
Effectively collect DNA test samples by wiping blood, epidermis and other tissues. Make the DNA test results more accurate, effectively avoid mixing with other magazines and affect the test results.
5. Cell sampling sterile swab.
The villus texture can collect more target analytes without sample residue. Speed up the sample processing.
The flocked tip swab: sterilized and packaged independently to improve the collection quality of cell collection swab!
6. Laboratory test sampling.
The villus texture can collect more target analytes without sample residue. Speed up the sample processing.
Why Flocked Swabs Provide Superior Specimen Collection？
What are the advantages of collecting DNA with flocked swabs?
Sample collection process: the unique structure at the top of the flocked tip swab can greatly increase the number of samples collected.
Sample precipitation process: the brush layer structure can release almost all collected samples.
The internal structure of the traditional cotton swab is formed by winding cotton fibers at its top. As a result, the precipitation efficiency of DNA with low content is lower, and even lead to false negative results.
The unique structure of the top of the flocked swab can almost completely extract and precipitate a small amount of DNA. Therefore, the flocking swab has more obvious advantages in micro DNA collection.
