The Measure of Excellence 7000 Series Syringes


HAMILTON 7000 series syringes are designed on the dead volume free principle of positive displacement. A fine tungsten plunger extends through the whole length of the syringe to the needle end. These syringes are available in capacities from 0.5 µl up to 5 µl. The accuracy is ± 1% of the nominal volume. The needle and tungsten plunger are exactly fitted and can be replaced as an assembly. Since the needle length and inner diameter determine the nominal volume when ordering special needles (SN) only the length and point style can be defined. Point style 5 needles are not available.


Typical applications are:


• Sample injection in GC • Sample pipetting in the sub microliter range in GC and TLC • Micropipetting •


Animal injections • Micro volume fluid transfers


Tech Tip The knurled hub is seated against a sealing ferrule at the junction of the needle/glass barrel, to ensure injection pressure. To maintain this seal periodically tighten the knurled hub nut until light resistance to plunger movement is felt. Use of pliers on the knurled hub nut may be required to achieve tightness.
