A complete range of dry swabs including cotton swabs, rayon swabs, dacron swabs in different sizes, and formats to suit most applications.
First select the swab shaft which can be standard plastic, fine plastic (very flexible and doesn’t break readily), straight wire (urethral) and fine twisted wire (paediatric and nasopharyngeal). Next the swab bud. For most clinical applications rayon, polyester, or polyurethane* are recommended. For some applications buds of calcium alginate, albumin coated, or cotton may be specified. Finally select the most appropriate presentation which is generally the swab in a labelled tube. If the tube is not required, most swab types can be supplied sterile in individual peel pouches, or even in bulk packaging.
*For swabs with open-celled polyurethane foam buds, see Sigma Dry.
