Nanoliter Injector Microinjection System from Harvard Apparatus

The Nanoject II is the latest development in the Nanoject family of microinjectors. One of the unique features of the Nanoject II is the use of a higher torque motor than in previous models. This new motor is smoother in operation resulting in substantially reduced tip movement. A new collect configuration holds the micropipette more securely thereby reducing air infiltration and oil leakage. The two-speed fill/inject mode will allow the user to fill and inject at half speed, facilitating the use of smaller micropipettes. The handling of more viscous samples will also be improved. All of the above factors enhance the precise delivery of sample. 

Volumes for the Nanoject II range from 2.3 nl to 69 nl. Although previous models of the Nanoject series are excellent for Xenopus injections, the smaller tips and smaller injection volumes of the Nanoject II allow users to perform injections into other specimens/applications that previously could not be performed. 

Positive displacement technology and the use of precision micropipettes, eliminate the need for tedious calibration when the viscosity of the sample changes. Contaminants in the sample do not hinder or change the injection volume as with some other injectors. An optional universal mounting adapter provides easy mounting of the Nanoject II to a variety of micromanipulators and stereotaxic frames.
