Tip - Rayon: Rayon, also known as Viscose, is a processed form of cellulose and has been found to be particularly suitable for the recovery of microorganisms. The texture is similar to that of cotton, but it has none of the fatty acids or other substances that can be inhibitory to fastidious bacteria. It has also been shown to be compatible with many molecular based diagnostic tests. Rayon buds are used on most of our transport swabs.
Traditionally, the bud on the swab has consisted of a spun fibre such as cotton, rayon, polyester or calcium alginate wound round the end of the shaft which would be wood, plastic or wire. In recent years, novel bud materials have been introduced, such as soft cellular polyurethane foam, or flocked fibres which can give improved uptake and release of specimens. Medical Wire have extensive ranges of swabs utilising either spun fibres, cellular foam, or multifilament flock fibres, with something suitable for many applications.
