Ace Glass 5929-02 Chromatography Syringe, 1 uL, 70 mm Long, 25 Gauge

For delivering liquid samples to a gas chromatograph with the very highest reproducibility and accuracy. The needle holds the entire sample. A tungsten wire plunger is individually fitted to the 0.152 mm bore of the stainless steel needle and bottoms at the tip of the needle to discharge the entire sample. A PTFE ferrule contained in the needle hub makes a final seal around the plunger at the base of the needle and is easily tightened to compensate for wear. Needle and plunger may be disassembled for cleaning or replacement.
