The Chemswab product contains 25 individually packaged urethane foam swabs that are pre-saturated with isopropyl alcohol (IPA). Chemswabs are used during maintenance of Rapiscan Systems’ (previously Morpho Detection) trace detection equipment for cleaning sensitive and hard to reach surfaces of potential contaminants. Failure to follow the regular maintained procedures outlines in your product manual may reduce the sensitivity of your equipment. Chemswabs are another important consumable accessory to include in the Explosive Detection equipment kit.
