GC Autosampler Syringes

Sigma-Aldrich offers a wide variety of syringes for autosamplers. Two brands of top-quality syringes, Hamilton and SGE, are offered which serve all major makes and models of GC and HPLC autosamplers.

Autosampler syringes are available in three different needle gauge styles to suit your particular application. The needles are constructed of narrow-bore stainless steel to minimize liquid dead volume, and have a special conical point that reduces the pressure needed to penetrate the autosampler septum.
  • 23s gauge needles - for standard injections
  • 26s gauge needles - for on-column and split/splitless injections.
  • 23s-26s dual gauge needles - allow you to perform all your applications without the need to change syringes.

Liquid and Gastight syringes in both Autosampler Fixed Needle or Autosampler Removable Needle styles. Dual gauge (23s-26s gauge, 1.7 inch length, point style #1 (cone shape) syringes combine the durability of a 23s-gauge needle with the performance capability of a 26s-gauge needle in split/splitless and on-column injection.
Available in two styles, the Gastight syringes are made with PTFE-tipped plungers.
