1. what is a flocking cotton sign?
Flocking refers to the process of applying multi-section fibers on the surface of adhesive coating; If there is flocking on the head of the
Cotton Swab, it is a flocking cotton sign.
It is a disposable sampling swab composed of nylon short fiber Velour head and ABS plastic rod. It is used for oral, nasopharynx, sampling, cervical vaginal sampling, laboratory testing, etc.
2、 Advantages of flocking cotton swabs
1. The sampling is more comfortable and convenient to use.
Our company adopts the existing technology "spray technology", through electrostatic charge flocking technology, millions of nylon microfibers are attached to the head of medical grade handle vertically. The function of the vertical nylon fiber is similar to that of soft brush, which is used to make the user feel free of foreign matters during sampling. At the same time, different breakpoints are used for flocking cotton swabs used in different parts. The thickness and softness of the rod are different.
For example, the upper axis of the nasal swab is thinner and softer, and the breakpoint is longer.
2. there are more samples released from flocking swabs.
Capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is retained on the surface, making elution easier. In traditional cotton swabs, most of the samples collected are still trapped in the fiber matrix of the head, which is not easy to release or release less. It has been shown that flocking swabs can release up to 95 percent of the samples, while standard fiber tip swabs can release 25 percent. If the sample size is particularly small, it is particularly important to use flocking swabs.
3. flocking swabs have biocompatibility, which is the ideal choice for PCR.
To limit damage to the sample and improve the accuracy of the test, swabs are made of completely inert parts. This makes flocking swabs very suitable for PCR work. Therefore, for scientists using PCR technology, the new flocking swabs are PCR compatible, without RNase and DNase.
instructions:
Prepare a cup of saline, drink about 50-100ml of saline, rinse for about 10-20 seconds, spit it out
Gently tear the bag of the oral swab, hold the handle of the oral swab with your hand (pay attention not to contact the head of the sampling swab with your hand and other objects), reach the left cavity of the inner wall of the mouth (contact the inside of the left cheek) and use the force of brushing and rolling up and down (wipe 15-30 times or so)
The second oral swab was taken in the same way and extended to the right side of the inner wall of the injection chamber for sampling. Continue to scrape the DNA samples of cells.
Put the collected oral swabs into the cell preservation solution, break the head, put them into the storage tube, paste the barcode, and put them back into the bag. Write down the name and date. Complete sampling. And then it's sent to the lab
