Synthetic polymer tubing made of polytetrafluoroethylene (Teflon). Polytetrafluoroethylene tubing is typically a small-diameter, hollow, flexible or semirigid cylinder designed for the transfer of fluids, either liquids or gases. Teflon 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 for the transfer of organic solvents or liquids when resistance to high pressure, chemicals, and/or temperature is needed.
