The Drummond Nanoject II Auto-Injector, now available from Alpha Laboratories, is specifically designed to perform ultra-delicate nanolitre injection procedures into cells, including oocytes and embryos.
Positive displacement technology and precision microcapillaries together with new features enhance the ease of use, precise delivery of sample and protection of cells.
The automated microprocessor control, delivers volumes from 2.3nL up to 69nL with complete accuracy and precision, even when sample contaminants are present.
Cells are protected by the remote controlled, non-rotating plunger that eliminates vibration, minimizing cell rupture.
Quieter and smoother, the new higher torque motor further reduces tip movement. A new collet configuration holds the microcapillary more securely reducing air infiltration and oil leakage.
The two speed mode allows the user to fill and inject at half speed, facilitating the use of smaller microcapillaries.
Handling of more viscous samples has also been improved, with no need for tedious recalibration if the viscosity changes.
The smaller tips and delivery volume of the Nanoject II enable injections into specimens other than Xenopus which were not previously possible with other models.
