Advantages of flocking swabs


Nylon swab: Excellent sample collection/release capacity, release rate > 80%.

Conventional fibre swabs:

Samples are intercepted by interstices within the fibre mass, i.e. samples are infiltrated, diluted and intercepted in the fibre. Collection is slower and release is slower.

The sampling time of flocking swab is 3-5 seconds, while that of cotton swab is 15-120 seconds, or even longer, which causes the pressure of staff in the process of diagnosis. Only by extracting samples faster, can the collection and analysis be completed more efficiently.

Extraction of DNA from microbiological samples by Huachenyang flocking swab and composite nano-cotton swab. Methods Three kinds of carriers (glass, one-character knife and drawer handle) were selected and disinfected to simulate the microDNA samples on the surface of the carriers. The microDNA samples on the carriers were extracted by Huachenyang flocking swab and composite nano-cotton swab respectively to detect the number of STR loci, the number of alleles lost and the peak height area. As a comparison index of extraction effect. Results Five microDNA samples were successfully extracted from Huachenyang flocking swab and four were effectively detected. Nine microDNA samples were effectively detected from the microDNA sample group extracted by composite nano-swab. The number of allele loss in composite nano-swab group was significantly higher than that in Huachenyang iClean group, and the peak area was significantly lower than that in composite nano-swab group. Bright morning sun. Conclusion The DNA extraction effect of Huachenyang flocking swab is better than that of composite nano-cotton swab on the fingerprint of glass surface, the exfoliated cells on the surface of open knife and the exfoliated cells on the surface of drawer drawer.

Characteristics of Huachenyang flocking swab

Huachenyang Medical Co., Ltd. uses a swab with spray dense nylon fiber technology.

According to the analysis items, there are soft or brush swabs corresponding to each other, which have reached the maximum amount of collection.

The only one-off sterile injection-moulded wiper rod with breaking point in the world.

The flocking cotton swab technology improves the amount of sample adsorption/release and the sensitivity of analysis.

No sample interception indicates faster and less sample transfer.

Upright nylon fibers, like a soft brush, can collect more cell specimens. The capillary interaction between nylon fibers enhances the load of water-borne samples, and the samples are concentrated on the surface of the swab, which is easier to elute. Nylon nasopharyngeal swab can absorb and release more samples.

Product characteristics:

  1. Made of non-suppressed DNA amplification material, which can be verified by direct PCR amplification, eliminating the extraction steps.
  2. Use separate packaging to avoid pollution.
  3. Strict technological conditions, free of DNA enzymes and amplified human DNA.
  4. The tube is transparent and the sample is intuitive and visible.
  5. The unique patented casing design ensures air circulation in the casing, prevents the material from mildewing due to the humid sealing environment, and avoids magazine pollution in the external air, thereby affecting the inspection quality.

Product advantages:

  1. Designed specifically for DNA micro-samples of crime scene, especially for sweat, semen, blood, dandruff, oral cells and other micro-samples with superior collection performance.
  2. It can adsorb trace samples quickly and has high release efficiency.
  3. The front end is pointed, which is suitable for the extraction of cells in the nail suture of the victim or suspect at the crime scene.
  4. The back end of the swab can be broken, which is helpful for the automatic extraction workstation to extract samples.
  5. The whole swab is packed in transparent plastic pipe to avoid biological pollution.
