<p>A fitting assembly (200) for use in an analytical instrument system, comprising: a nut (210) having a first end (211)and a second end (213) and a passageway (222) therethrough, a nut head (212) proximal to said first end of the nut, an externally threaded portion (214), an external lip (217), and a first externally tapered portion (215) proximal to said second end of the nut; and a ferrule (230) having a first end (236), a second end (237), an internal lip (232) proximal to said first end (236) of the ferrule, and a passageway (235) therethrough, wherein said passageway of said ferrule comprises an internally tapered portion proximal to said second end of said ferrule, and wherein said internal lip of said ferrule is adapted to securely engage with said external lip of said nut. The nut and ferrule fitting assembly may be adapted for use with a flat bottom port, such as in an analytical instrument, like liquid chromatography, gas chromatography, ion chromatography, or in in vitro diagnostic systems.</p> |
