Let Gravity Take Control.

Our Portable Pipet-Aid® XP Gravity shares many features with our standard XP model but with two significant differences.  Alongside the burgundy-colored buttons, clip, and nosepiece, the fast setting now features a gravity (G) setting that allows the pipette to dispense its contents without turning on the pump.  This method is most familiar with volumetric pipettes.

  • Lightweight
  • 3 speed settings for aspiration
  • Gravity setting allows for dispensing without turning on pump

What XP Gravity Portable Pipet-Aid® with 110V Users Say

The New Nanoject III Is Now Available!

Nanoject II vs. Nanoject III Comparison

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.
