Microinjection

Microinjectors are often used in genetic engineering and research, organism cloning, and in cell biology and viral studies. Clinical applications include in vitro fertilization, intracytoplasmic sperm injection, Organoids, Zebrafish, C Elegans, and Xenopus to name a few. Microinjection products are more technical and niche. Using technology that has been improved and innovated repeatedly since the 1990s, the third generation Drummond Nanoject III is incredibly accurate offering the specificity required for this type of measurement. Microinjectors are not to be used on humans.

Precise Microinjectors Through Innovation

Microinjection is the process of inserting genetic material into an animal cell or embryo using a glass micropipette/injection needle to penetrate the cell membrane. It is essentially a microscope with an incorporated micromanipulator for precise needle positioning.

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.
