  • Modified fluoropolymer tubing for robust fluid stream continuity and method of manufacture
    Patent number: 9651198
    Abstract: The present invention discloses a section of tubing including a fluoropolmer tubular body which has an interior surface defining a fluid passage through the tubular body. At least a first portion of the interior surface has a first hydrophobicity which is less than that of the remainder of the tubular body. At least a first portion of the interior surface can have a molar ratio of fluorine to oxygen of no greater than 30 to 1. Products can include the tubular bodies of the present invention attachable to fluid processing instruments such as immunodiagnostic instruments. The present invention also discloses methods for manufacturing the disclosed tubular bodies.
