SGE* Plunger-in-Needle Syringes

With the ability to inject down to 0.1 µl with high precision and accuracy better than 2%, these plunger-in-needle syringes are perfect for microvolume capillary chromatography injection. The capacity of these syringes is so small that the entire sample is contained within the needle portion of the syringe. The plunger extends to the tip of the needle, displacing the full sample during injection, giving the syringe virtually zero dead volume. A sheath and guide tube protect the plunger wire during the injection stroke. A seal between the plunger and needle permits high pressure injection. 8 mm OD barrel, cone needle tip.
