Medium-free systems prevent specimen dilution and contamination that can occur with devices containing transport media

Systems feature swabs with a special polyurethane open-celled structure that releases organisms from their environment and protects them during transport. Swabs have a 13.3cm (5¹/₄") long shaft to reach tough sampling sites. They fit into round-bottom transport tubes that stand upright in traditional racks for easy transportation. The caps for the transport tubes are color-coded for easy identification and the double action seal prevents dried out or leaky samples for increased safety.
