Abstract
Coextruded plastic capillary tube and method of manufacturing a coextruded tube for collecting a volume of liquid. The tube is disposable, inexpensive to manufacture and can reliably draw blood and other aqueous based fluids into the tube by capillary action, at a fluid uptake level comparable to glass and other commercially pre-treated plastic tubes, without requiring further interior coating.
