What is the difference between flocking swabs, sponge swabs, and ordinary cotton swabs?

The flocking swab is mainly composed of a nylon short fiber fluff head and ABS plastic rod, which is a kind of disposable sampling swab. The head of the flocking swab is a neat nylon short fiber bundle with a regular structure and a brush-like structure, with each nylon fiber perpendicular to the base.

The special structure of the flocked swab head can make the entire sample collection area without internal absorption holes, and the capillary action between nylon fiber bundles promotes strong hydraulic absorption of liquid samples, and its adsorption force is very strong in collecting viruses and DNA; The collected sample remains on the surface of the fiber bundle, will not disperse and stay in the fiber, which makes the elution easier and also has a better release rate. The flocked swab head has a large contact area and a long handle. Its fast adsorption capacity and excellent release efficiency provide protection for limited or trace amounts of DNA, and it is especially suitable for the extraction of exfoliated cells on outdoor sites and in contact.

Sponge swabs are made of layers of mesh cotton and are often used to moisturize the mouth and help loosen thick mucus secretions, food scraps, and thickened saliva, and are also commonly used in eye surgery. The structure of the sponge swab head is a mesh structure, and it is difficult for microorganisms to be released after entering the inner mesh.

Traditional cotton swabs are made of thousands of meters of fibers wrapped around the top of a plastic rod. It is an important piece of equipment for collecting biological evidence. It is suitable for the sampling of mucous membranes and wounds and is often used to extract biological samples.

The swabs created a matrix environment with many gaps in the arrangement. Cells and microorganisms that have been collected after sample collection are trapped in these crevices, trapped in the fibrous matrix of the head, and difficult to be released. Flocked swabs are biocompatible and ideal for PCR work.https://hzrollmed.com/
