Both units utilize the same glass capillaries for pulling micropipettes; however, note that significantly smaller pipettes can be used with the Nanoject III due to the new improved method of securing the micropipette. No O-rings to wear out are used. A micro ?chuck? is used that is not a wear item and it simplifies attachment of the micropipette once backfilled with oil.
The auto HOMING feature will eliminate the need to ?rehome? the unit as in the Nanoject II and this will reduce if not totally eliminate jamming of the plunger.
The new Drummond Programmable Nanoject III Nanoliter Injector offers a number of state-of-the-art features to provide easy setup and operation as well as more accurate injection volumes down to 0.6 nanoliters. The Nanoject III does not require any O-rings to secure the micropipet. Operational Modes enable the user to program the unit to do single manual injections, as well as multiple injection cycle recipes. Program input and execution is enabled by prompted touchscreens located on the control box. Programmability, the lower injection volume capability plus the user's ability to select the injection rate widens the potential range of applications for the Nanoject III. The Universal Power Source provides adapter plugs to enable the unit to be used in the US, UK, Europe, and Australia simply by inserting the proper plug.
