The flocking swab is to deposit nylon fibers on the surface of the medical ABS rod in a certain direction through the electrostatic field to form a brush layer, and the layers are sufficiently parallel and perpendicular to the surface of the inner rod, through this The brush head is used for DNA collection, which can be used for the sampling of natural human cavities such as the mouth, nasopharynx, etc., and can also be used for laboratory testing.
And after hundreds of experimental analysis, it was found that the extraction efficiency of nylon flocking swabs
was the highest.
What are the advantages of flocked swabs
Compared with the traditional winding swab, the amount of samples collected and released by flocking swabs is 3 times higher, and it will not cause harm to the human body.
·Sampling is comfortable and easy to use. Flocking swabs are now basically using 'spray-on technology', which vertically attaches millions of nylon fibers to the head of the medical ABS swab shaft through the flocking process of electrostatic charge. The vertical nylon fibers act like a soft brush, which allows the user to feel free from foreign objects during sampling. At the same time, the flocking swabs used in different parts have different breaking points, and the rods use different thicknesses to make the softness different.
The time for flocking swabs to collect samples is 3-5 seconds, which is fast and convenient to improve work efficiency. Only faster sample extraction can complete the collection and analysis more efficiently.
And through the directional friction effect of the brush-like fiber layer, the cell sample can be completely captured, so the flocked swab
is particularly beneficial for the collection of trace DNA.
After a large number of clinical experiments, it has been shown that compared with ordinary sterile cotton swabs, flocked swabs have better collection and transportation effects on clinical microbial specimens. This is especially true for those specimens that cannot be submitted for inspection in time and that have been placed for too long.
