The Portable Pipet-Aid XL Reduces Fatigue When Pipetting Under a Hood

Researchers are often required to perform many bioassays which involve a great deal of Pipetting. Much of this type of work needs to be performed under a biological safety hood which requires the user to pipet using tedious arm positions and motions. Using conventional pipettors over extended periods many people have reported nerve damage and carpal tunnel syndrome. The design of the Drummond Pipette-Aid XL was developed to alter the required pipetting motion that seemed to be causing the problem. The longer, lightweight handle enables the user to rest his or her elbow on the front edge of the hood counter and shortens the motion required to perform the same pipetting operation as with a conventional pipettor. The result is substantially reduced strain on the user’s shoulder, arm, and hand. Drummond has received numerous testimonials from actual users reporting the benefits of the ergonomic design of the Pipet-Aid XL. Some of these testimonials can be reviewed here.

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.
