Both units utilize the same glass capillaries for pulling micropipettes. Due to the new improved method of securing the micropipette, smaller tips can be pulled and utilized on the Nanoject III. No O-rings to wear out. A micro “chuck” is used, and it simplifies attachment of the micropipette once backfilled with oil. The Nanoject III’s auto HOMING feature will eliminate the need to “rehome the unit as in the Nanoject II. This can reduce, if not totally eliminate, jamming of the plunger. Now available for the Nanoject II is the new Digital Control Box which has all the functionality of the original control box but now features a user friendly, easy to read touchscreen.
