ABSTRACT OF THE DISCLOSURE A needle interface apparatus for maintaining a stable connection between a first instrument and a second instrument, such as an autosampler unit and a gas chromatograph. A needle interface apparatus is comprised of a modified septum nut on the second instrument which has a nipple, and a needle assembly having a sleeve positioned around the needle wherein the sleeve frictionally fits over the nipple of the modified septum nut. A support tube surrounds the needle assembly and connected transfer line from the first instrument to minimize flexing of the outlet tubing relative to the needle assembly.
