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.
