Now sampling swabs include ordinary cotton swabs and flocking swabs. Many people do not know what the advantages of this flocking swab are? What are the advantages of flocking swabs over cotton swabs?
1. Flocking swabs are more comfortable for sampling and easy to use.
Today's flocked swabs use existing technology 'spraying technology' to vertically attach millions of nylon fibers to the head of a medical handle through electrostatic charge in the flock. The vertical nylon fibers resemble a soft brush. If this soft brush is used during sampling, the user will have no foreign body sensation. In addition, different parts, different bending points of the flocking swabs used, and different thickness of the handle, so the softness is very different. For example, for nasal swabs, the upper end of the rod is thin and soft, with a long break point.
2. The release of flocked sampling swab samples is larger
The capillary action between the nylon fiber bundles promotes the strong hydraulic absorption of the liquid sample, which keeps the sample on the surface and is easy to dissolve. The samples collected by cotton swabs previously were mostly still blocked by the fibrous matrix of the head and released in small amounts. Flocked swabs have been shown to release up to 95% of the sample, while standard fiber-tipped swabs can release 25%. The use of flocked swabs is especially important when the sample volume is particularly small.
3. Flocked swabs are biocompatible
In order to limit the damage of the sample and improve the inspection accuracy, the cotton swabs are completely made of inert materials. So flocked swabs would be ideal for PCR. Therefore, for scientists using PCR technology, the new flocked swabs are PCR compatible and free of RNase and DNase.
What is flocking:

Flocking refers to the process of applying monofilament fibers to the surface of the adhesive coating. There is almost no difference between him and the cotton swab except that the material is different. It can also be said that flocking is bonded to the head of the cotton swab. Then it is a flocking swab, but unlike cotton swabs, it is a disposable sampling swab made of nylon short fiber fluff ABS plastic rods. It is mainly used for sampling of human natural orifices (oral cavity, nasal cavity, throat and vagina, etc.) and laboratory examination.
