Speaking of sexual sampling swabs
, I believe that everyone is familiar with it during this time, because most of the testing tools used in nucleic acid testing are disposable sampling swabs.
Disposable sampling swabs, also called sampling sticks, can be made of cotton, polyester or nylon. However, compared with the first two materials, flocking swabs can collect a large number of cell samples and quickly wash and release them into the culture medium. This product is widely used in nucleic acid detection, antigen detection, molecular genetics, forensics and clinical experiment production of new crowns.
Sampling swabs are in direct contact with our human organs, such as nasal swabs and throat swabs for nucleic acid testing, so the material selection of the sampling head is very important, and the material of the sampling head is closely related to subsequent testing. Sampling swabs should ensure the sampling volume and release volume, and the selected materials must not contain substances that affect subsequent detection.
Advantages of Flocked Sampling 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.
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 a better effect on the collection and transportation of 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.
