The tip of DNA flocking swab is nylon flocking fiber structure, and the brush-like layer is formed on the surface of medical ABS plastic rod by attaching nylon fiber in the direction with electrostatic field, and the layers are fully parallel and perpendicular to the surface of the internal rod, and DNA collection has been carried out with this brush head.

At present, the flocked swab of Shenzhen Huarui Kang Biomedical Technology Co., Ltd. has obtained relevant certificates and has obtained export rights in many countries.

Benefits of flocked swab for DNA collection.

1、Sample collection process: The unique structure of the front end of flocked swab can significantly increase the number of collected samples.

2、Sample lysis process: The brush-like layer structure can release almost all collected samples.

More advantageous for trace DNA collection.

In the past, due to the internal structure of the tip fiber entanglement, the sample was dispersed in the fiber mass and stagnated in the fiber during collection, which reduced the efficiency of DNA precipitation that was otherwise low, and may also cause false negative results of the test. The unique structure of the flocked swab tip allows for almost complete extraction and precipitation of even very small amounts of DNA, making the flocked swab a more obvious advantage for trace DNA collection.

Principles of DNA collection and precipitation by flocked swabs.

(1) Cell samples can be completely captured by the directional friction effect of the brush-like fiber layer

(2) The cell samples are all concentrated on the near surface of the brush fibers, so that about 9.5% or more of the sample can be released eventually.

(3) Capillary motion between the nylon fibers at the front of the flocked swab creates a strong hydraulic pressure used to absorb liquid or cell line samples.

How to use the DNA flocking swab.

(1) First open the swab package and carefully remove the swab, taking care not to touch anything before taking the sample to avoid contamination.

(2) Put the swab into the place to be sampled, and sample by staying, rotating or wiping

(3) Gently remove the swab, usually by placing the swab into the virus collection tube, removing the end of the swab after breaking it at the fracture and tightening the cap to remove it quickly for examination.
