Forensic evidence dryers designed to remove moisture from swabs containing forensic evidence (e.g., blood, body fluids) using forced air to ensure that the samples are dry. These dryers typically consist of a small tabletop or wall-mounted enclosure (typically of less than 55 cubic dm [2 cubic feet]) with a forced-air source (usually a fan) and a rack for swabs that may be independent from the enclosure. The devices also include air intake and exhaustion filters (e.g., HEPA) and a timer. Swab dryers are intended to dry wetevidence (e.g., of sexual assault) samples (typically swabs impregnated with body fluids) before further processing, reducing the risk of cross-contamination.
