Product description: Sterile flocking swab

This product is produce by Brilliance Yangxin nylon flocking technology, international patent production technology.

A large number of clinical and forensic DNA tests by the Ministry of Public Security at home and abroad have shown that: Compared with ordinary sterile swabs,

nylon flocked swabs have a better effect on the collection and delivery of clinical biological samples, especially for those who cannot be sent for inspection in time.

This is especially true for samples that have been place for too long.


1.Connection strength: when the moving speed of the tensile testing machine fixture is 200 mm/min;

the pull-out force of the sampling head and one end of the connecting rod should not be less than 2N.

2.Breaking strength: When the test span is 6cm,

the swab should be able to withstand 4N axial static pressure for 15s without permanent deformation or breaking.

3.Rotational friction: After spraying the glue on the ABS rod, the flocking is spray.

The abrasion fastness means that the test is not more than 2N, the rotation friction is not less than 3 times,

and the amount of denying hair on the surface is not more than 2.


Nylon flocking swabs are widely used in genetic testing and sampling, cytology, microbiology,

bacteriology sample processing, virology cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing,

polymerase chain reaction and based Molecular diagnostic testing and forensic identification are ideal.

It can also be used for throat sampling of respiratory viruses such as influenza, swine flu, avian flu, hand, foot and mouth.


What are the characteristics of flocking swabs

What are the characteristics of flocking swabs

The top of the flocking swab is make of nylon fibers.

The nylon fibers are sequentially attach to the surface of the medical ABS rod through an electrostatic field.

The layers are completely parallel between the layers and perpendicular to the surface of the inner rod for DNA collection.

The principle of flocking swab in DNA collection and precipitation

1.Through the directional friction effect of the swab fiber layer, the cell sample can be completely captured.

2.Since the cell samples are concentrate near the surface of the swab fiber, more than 95% of the sample can be release eventually.

3.The capillary movement between the nylon fibers at the top of the flocking swab forms a powerful hydraulic pressure, which is use to absorb liquid or cell samples.

What are the advantages of flocking swabs for DNA collection?

1.Sample collection process: The unique structure on the top of the swab can greatly increase the number of samples collected.

2.Sample dissolution process: Because the samples collecte by the swab are basically on the surface of the swab, 95% can be release, which means that almost all samples can be wash out.

Why flocking swabs are more beneficial for micro-DNA collection

1.The top of the traditional cotton swab is an internal structure wound with cotton fibers.

When sampling, the fiber clusters are disperse and remain on the fibers, resulting in a decrease in the extraction efficiency of the original low-content DNA, and may even lead to false negative results in the test.

2.The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA.

Therefore, the flocking swab has a more obvious advantage in collecting trace DNA.

How to use flocking swabs

1.Open the swab package first, take out the swab carefully, and take care not to touch anything else before sampling to prevent contamination.

2.Place a swab on the place where the sample is needed, and sample by retention, rotation or friction.

3.Gently take out the swab. Generally, put the swab into the virus sampling tube, break it at the point where the swab breaks,

throw away the end of the swab, tighten the cap, and send it for inspection as soon as possible.

Why use a virus sampling tube?

Why use a virus sampling tube?

A virus is a small substance compose of nucleic acid molecules and proteins or only of proteins.
It is small in size and simple in structure.
Since there is no cell structure, the virus itself cannot replicate, so the gene is invad into the host cell, and new viruses are replicate with the help of the latter’s replication system.

After the virus sample is collecte, in order to maintain the viability of the virus sample and prolong the survival time of the virus in the sample, the sampling swab will be store and transport in the preservation solution.

How to use virus preservation solution:

①. Before sampling, note the relevant virus sampling information on the label of the sampling tube;

② According to different sampling requirements, use a sampling swab to sample at the corresponding part;

③. Put the sampled swab vertically into the virus sampling tube;

④. Break the sampling swab at the broken place, discard the tail, and tighten the tube cap

④ Put it in a biosafety bag and send it for inspection in time
