Introduction and characteristics of sterile swabs

Sterile swabs, full-name disposable sterile sampling swabs, not only for bacteriological sample processing, COVID-19, nasal swab sampling, throat swab sampling, oral swab sampling, but also for virus cell culture , DFA detection, rapid direct detection, enzyme immunoassay, polymerase chain reaction based on molecular diagnostic tests and forensic identification are ideal choices.It can also be use for throat sampling of respiratory viruses such as influenza, swine flu, avian flu, hand, foot and mouth.

Scope of application

The best tool for skin surface sampling, DNA collection, oral cells, physical surfaces, microorganisms, bacteria and viruses testing and sampling. The disposable aseptic sampling swab CY-98000, with a break point of 3cm, is superior in that it is better than traditional swabs, The collection and release volumes are large and can be broken. The traditional swabs need to be cut by the laboratory staff with scissors, which is too troublesome and too time-consuming. Our new flocking disposable sampling swab greatly reduces the time cost.


  1. It not only has excellent water absorption capacity, but also can increase the number of specimens collected on the watch from 20% of the traditional sampling swab to 60%.
  2. The release rate of the collecte specimens exceeds 90%, thus ensuring the high reliability of the results.
  3. Different preservation solutions are selecte for different types of specimens.
  4. The unique easy-to-break design on the plastic rod is not only convenient for transporting specimens, but also particularly suitable for preservation
  5. We not only use ethylene oxide for sterilization, but also for irradiation sterilization, but also individually packaged.

DNA aseptic flocking swabs are suitable for humans and animals, and have advantages over other DNA test samples in design. Its unique test sample matrix and rapid release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilize with ethylene oxide and passed the test for human DNA contamination.

What are the advantages of oral swabs?

The toothbrush-type oral swab launched by Huachenyang not only solves the problem of high efficiency and storage of cells,

but also solves the dilemma that China has no special tools for collecting oral cells in recent years.

Not only do not worry about the frequency and amplitude of scrubbing, but also do not worry that some deviations caused by these factors will affect the subsequent storage and test results.

Advantages of Huachenyang oral swabs:

(1) Huachenyang oral swab not only uses polyester fiber technology, but also accelerates the absorption of the sample and speeds up the release of the sample

(2) Not only can the maximum elution and transfer of samples, but also those used to collect trace amounts of DNA samples

(3) The novel push head design makes the swab not only easy to sample and push it directly into the sampling tube, but also the sampling swab head will drop into the sampling tube, making it easier to handle.

(4) Not only is it individually packaged, it is also sterile and inhibitor-free, ensuring reliable results.

(5) Different preservation solutions can be selected for different types of specimens.

(6) Special treatment with antibacterial agents to prevent microbial contamination

(7) Adopt internationally accepted medical dialysis paper-plastic packaging which is convenient for sterilization.

Cotton swabs (American English) or cotton buds (British English) or ear buds (Australian and South-African English) consist of a small wad of cotton wrapped around one or both ends of a short rod, usually made of either wood, rolled paper, or plastic. They are commonly used in a variety of applications including first aid, cosmetics application, cleaning, and arts and crafts. The cotton swab was invented in the 1920s by Leo Gerstenzang after he attached wads of cotton to toothpicks. His product, which he named “Baby Gays”, went on to become the most widely sold brand name, “Q-tips”, with the Q standing for “quality”. The term “Q-tips” is often used as a genericized trademark for cotton swabs in the USA.

Although doctors have said for years that usage of the cotton swab for ear cleaning is not safe, that use remains the most common.


The traditional cotton swab has a single tip on a wooden handle, and these are still often used, especially in medical settings. They are usually relatively long, about six inches (15cm). These often are packaged sterile, one or two to a paper or plastic sleeve. The advantage of the paper sleeve and the wooden handle is that the package can be autoclaved to be sterilized

(plastic sleeves or handles would melt in the autoclave).

Cotton swabs manufactured for home use are usually shorter, about three inches (7.6cm) long, and usually double-tipped. The handles were first made of wood, then made of rolled paper,

which is still most common (although tubular is also used). They are often sold in large quantities, possibly 111 or more to a container. Swab stems exist in a wide variety of colors, such as blue, pink or green. However, the cotton itself is traditionally white.


Huachenyang Flocked Swabs Manufacture


Not like traditional fiber swabs, HCY flocked swabs don’t have an internal absorbent core to disperse and wrap the sample. The entire sample is close to the surface for quick and complete replacement. The capillary action between the vertical nylon fiber bundles promotes the strong hydraulic absorption of the liquid sample. The sample stays close to the surface for easy replacement.

Why use flocking swabs:

Comparison of flocking swabs:

Implanted nylon swab: excellent sample collection/release ability, release rate>80%

Conventional fiber swab:

Voids in the fiber mass retain the sample,In other words, the fiber penetrates, dilutes and intercepts the sample as it enters

The acquisition is slow, and the release is slower.

The sampling time of flocking swab is 3-5 seconds, while the sampling time of cotton swab is 15-120 seconds, or even longer. Therefore, the staff will have a lot of pressure in the diagnosis process. Only faster samples can be collected and analyzed more efficiently.

Features of Huachenyang flocking swab:

①. It is made of non-inhibitory DNA amplification materials, and it has been verified that it can be directly amplified by PCR, eliminating the need for extraction.

②. Single and independent packaging is used to avoid pollution.

③. Strict process conditions, without DNase and amplifiable human DNA.

④. The tube body is transparent, and the inspection materials are intuitively visible.

⑤. The unique patented casing design ensures the air circulation in the casing, so that the sample material will not mildew due to the humid and sealed environment, and there will be no magazine pollution in the outside air, thus affecting the inspection quality.

Product advantages:

①This design is able to sample DNA micro samples, which is most suitable for crime scene, especially for sweat, semen, blood, dandruff, oral cells and other micro samples, with excellent collection performance.

②.It can not only quickly adsorb a small amount of samples, but also has high release efficiency.

③. Not only is the tip of the needle sharper than before, but it is more suitable for extracting cells from the fingernails of victims or suspects at the crime scene.

④The back end of the swab can be broken off, which is conducive to the automatic extraction workstation for sample extraction.

⑤. Packing the whole swab in a transparent plastic tube can avoid biological contamination.
