The 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 needle end. These syringes are available in capacities from 05ul up to 5 uL. 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:
1) Sample injection in GC
2) Sample pipetting in sub microliter range GC and TLC
3) Micropipetting
4) Animal injections
5) Micro volume fluid transfers
