Now sampling swabs are divided into ordinary swabs and flocked swabs, many people do not know what the advantages of this flocked swab? Flocked swabs are better than ordinary swabs in what?
Flocked swabs are more comfortable to sample and more convenient to use.
Nowadays, flocked swabs use the existing technology "spray technology", which is to make millions of nylon fibers vertically attached to the head of the medical swabbing rod by electrostatic charge in the flocked hair. The vertical nylon fibers resemble a soft brush. If this soft brush is used in the sampling process, the user will have no foreign body sensation. In addition, the fracture point of the flocked swab used differs from site to site, and the thickness of the swabbing rod also varies. Therefore the softness varies greatly. For example, in nasal swabs, the upper end of the swabbing rod is thin and soft, and the break point is also more posterior.
Flocked swabs have a large sample release and high sampling efficiency
The capillary action between the nylon fiber bundles promotes strong hydraulic absorption of the liquid specimen, keeping the specimen on the surface and easily dissolved. Most of the samples previously collected by ordinary swabs remained blocked by the fibrous matrix of the head, with low sampling and release. It was demonstrated that flocked swabs can release up to 95% of the sample, while standard fiber-tipped swabs can release 25%. The use of flocked swabs is particularly important when sample volumes are particularly low.
Flocked swabs are biocompatible
To limit sample destruction and improve examination accuracy, flocked swabs eschew the inert material of previous common swabs. Flocked + ABS rods are free of RNA and DNA enzymes and are compatible with PCR, making them ideal for scientists using PCR technology.
