The sampling swab adopts flocking swab. Compared with conventional fiber swabs, the sample is easily trapped by the gap in the fiber mass, that is, the sample is penetrated, diluted, and intercepted in the fiber. The flocking swab adopts the unique jet implant nylon flock technology, which has excellent sample collection and release capability, and the release rate can reach 90%, which is much higher than that of the fiber swab.
