Hamilton 1 μl, Model 7101 KHWG Syringe, knurled Hub, with Guide, 25s Gauge, 70 mm, point style 3

Hamilton's 7000 series, Microliter #7001 Knurled Hub (KH) Syringe is designed for manual dispensing and use in autosamplers. The Syringe Guide comes with this syringe installed from the factory. This eliminates the assembly step, which can lead to damage of the smaller volume syringes.
