The same medical swab, how cotton swabs and flocked swabs there is a difference? That flocked swab compared to cotton swab, flocked swab in the end where is better than cotton swab a chip?
1. flocked swab sampling than cotton swab sampling to be more comfortable, more convenient to use.
First of all, flocked swabs are now commonly used "spray technology", through the electrostatic charge in the flocking process vertically millions of nylon fibers attached to the head of the handle for medical use. Such vertical nylon fibers are similar to a soft brush. This makes the user feel comfortable during the sampling process without any foreign body sensation. At the same time, the flocked swab can take different break points according to different parts of the sampling needs, and the rod can also be used in different thicknesses so that the softness becomes different, such as nasal swabs, the upper end of its rod will be more thin and soft than other swabs, and the break point will be longer.
The traditional cotton swab can generally only be used for mycoplasma testing vaginal, cervical and urethral specimen collection, and not for bacteria (especially caustic bacteria), chlamydia test specimen collection. In this way, cotton swabs are not as applicable as flocked swabs.
2. Flocked swabs have a greater release of samples than cotton swabs
Secondly, the capillaries between the nylon fibers used in flocked swabs will promote strong hydraulic absorption of the liquid sample, keeping the sample on the surface. And flocked swabs have been shown to release up to ninety-five percent of the sample. This makes elution in subsequent testing easier than cotton swabs, and the test results will be more accurate.
In contrast, the traditional standard fiber tip swab can release up to twenty-five percent. If the sample size is particularly small, the use of flocked swabs is particularly important.
3. Flocked swabs are biocompatible, making them ideal for PCR work.
Furthermore, to limit damage to the sample and to improve the accuracy of the assay, swabs have completely inert materials made of. Moreover, most of the samples collected by traditional cotton swabs will be intercepted in the fiber matrix and will not be easily released or released in small amounts, which will have a great impact on the subsequent assay.
In contrast, flocked swabs are PCR compatible and free of RNA enzymes and DNA enzymes, making the new flocked swabs ideal and the best choice for scientists using PCR techniques.
