Abstract

A inert sampling needle is provided for piercing a septum of a vial containing a sample. The sampling needle includes a hollow rigid support member having an inner wall, an outer wall, and a septum-piercing end. The sampling needle also includes a sheath member affixed to the rigid support member. The sheath member covers the septum-piercing end of the support member, the inner wall, and at least a portion of the outer wall adjacent the septum-piercing end to isolate the support member from the sample. Preferably, the sheath member is formed of polyetheretherketone and is affixed to the rigid support member by heat fusing. A method of forming, and a method of using the inert sampling needle is also disclosed.
