UMD: Synthetic polymer tubing made of a clear polyvinyl plastic substance modified with plasticizers for flexibility (Tygon). Tygon tubing is typically a small- or medium-diameter, flexible hollow cylinder designed for the transfer of fluids, either liquids or gases. Tygon tubing is usually available in standardized lengths and in a variety of diameters and wall thicknesses (i.e., gauges) that permit the use of segments of different sizes appropriate for a given application in the healthcare facility (e.g., clinical laboratory), especially when high resistance to chemicals is needed.
