Advantages of flocked swabs

Blog swabs1941

Regular fiber swabs:

The sample will be trapped by the gaps in the fiber mass, that is, the sample will be penetrated, diluted, and trapped within the fibers. The acquisition is slow, the release is even slower.

The time for flocking swabs to collect samples is 3-5 seconds, while the time for cotton swabs is 15-120 seconds, or even longer, which causes pressure on staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

The extraction effect of Huachenyang’s flocking swabs and composite nano-cotton swabs on the DNA of trace biological samples. Methods Three common carriers (glass, slotted knife, and drawer handle) were selected and disinfected, and decontaminated to simulate trace DNA samples on the surface of the carrier. The number of detected STR typing loci, the number of lost alleles, and the peak height area were used as the comparison indicators of the extraction effect. Results In the micro-DNA sample group extracted by Huachenyang flocking swab, 5 micro-DNA samples were successfully detected, and 4 were effectively detected; 9 micro-DNA samples were effectively detected in the micro-DNA sample group extracted by the composite nano-cotton swab; The number of alleles lost in the cotton swab extraction group was significantly more than that of Huachenyang iClean, and the peak height area was significantly lower than that of Huachenyang. The DNA extraction effect of Huachenyang flocking swabs on glass surface fingerprints, exfoliated cells on the knife surface, and exfoliated cells on the drawer handle surface in this study was significantly better than that of composite nano-cotton swabs.

Features of Brilliance Flocking Swabs:

Huachenyang Medical uses swabs with densely planted nylon fiber technology.
According to different analysis items, there are soft or brush texture swabs, which have reached the maximum collection volume.
The world’s only disposable sterile injection-molded swab rod with the breakpoint.
The flocked swab technology increases the adsorption/release of the specimen and improves the sensitivity of the analysis.
No sample entrapment, heralding faster, and less sample transfer.
The upright nylon fibers act like a soft brush to collect more cell samples. The capillary action between nylon fibers enhances the loading of aqueous samples, and the samples are concentrated on the surface of the swab for easier elution. Nylon nasopharyngeal swabs can absorb and release more samples.


1. Made of non-inhibitory DNA amplification materials, verified by direct PCR amplification, omitting the extraction step.
2. Use a single independent packaging to avoid pollution.
3. Strict process conditions, free of DNase and amplifiable human DNA.
4. The tube body is transparent, and the condition of the inspection material is directly visible.
5. The unique patented casing design ensures air circulation in the casing, prevents the test material from mildew due to the humid and sealed environment, and avoids magazine pollution in the external air, which affects the inspection quality.

Product advantages:

1. It is specially designed for DNA trace samples at crime scenes, especially for trace samples such as sweat, semen, blood, dander, oral cells, etc. It has excellent collection performance.
2. It can quickly adsorb trace samples and has high release efficiency.
3. The front end is sharper, which is suitable for the extraction of cells from the fingernails of crime scene victims or criminal suspects.
4. The rear end of the swab can be broken off, which is conducive to the extraction of samples by an automated extraction workstation.
5. The whole swab is packaged in a clear plastic tube to avoid biological contamination.
