In just two years from 2020 to 2022, the new crown epidemic became the most familiar word to us. We had to do nucleic acid tests regularly and the test reports became indispensable proof of travel. I can't count the number of times my throat has been stabbed with a thin stick, the number of times I've dry-heaved, and my throat has been poked with calluses. And these "stick" is our protagonist today - nucleic acid antigen test swab.

1, what is the nucleic acid antigen detection swab?

Nucleic acid sampling swab, or flocked swab, its head material is used nylon microfiber, small brush-like shape is ideal for rapid absorption of fluid samples from irregular surfaces, and can be collected to thoroughly release the sample into the culture fluid, soft bristles can also reduce the discomfort of the sampled person.

The handle of the sampling swab is generally made of polystyrene (or ABS) with a break point designed in the middle for easy fracture to put into the sealed bottle.

2、What is the raw material of nucleic acid antigen detection swab?

Flocking: niflower

Flocking glue: flocking glue (polypropylene)

Sampling rod material: polystyrene

Know what is nucleic acid detection antigen detection swab, many people may be more concerned about nucleic acid antigen detection swab in the end how the production?

3, nucleic acid antigen detection swabs common production process.

Injection molding --- dipping flocking glue --- centrifugal flocking --- electrostatic flocking --- baking --- finishing --- inspection --- packaging

Firstly, inject the swab stick by automatic injection machine, install the swab stick on the bracket, impregnate the flocking glue centrifugally to shake off the excess glue, put it into the flocking box for flocking, then dry it in the drying channel, sort out and inspect it after drying, and finally pack it into nucleic acid sampling swab products.

Principle: The principle of electrostatic flocking is to make use of the physical property that charges repel each other and attract each other, so that the flock is negatively charged. Electrostatic flocking is a new production process that makes use of the natural characteristics of electric charge.

Of course, the above introduction is only the more common swab production process, different companies nucleic acid antigen detection swab production process details may be more or less different.
