Typically having heads manufactured of polyester knit fabrics, swabs for sampling have the lowest level of released particles and highest sample recovery rates. After lightly moistening, the flexible applicators can pick up residue from any shape surface before sample is eluted for analysis. The single- or double-tipped collection devices utilize a less destructive method than bulk sampling. Pre-cleaned for immediate use, the disposable sampling swabs guarantee that tests remain uncontaminated.
