Positive displacement technology and precision microcapillaries together with unique 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, minimising cell rupture. The narrow tips and delivery volume of the Nanoject II enable injections into specimens other than Xenopus. Quieter and smoother than former models, the higher torque motor further reduces tip movement. A novel collet configuration holds the microcapillary more securely reducing air infiltration and oil leakage. The Nanoject II Kit includes the following components: ■■Injector head with lead ■■Control box ■■Power supply ■■Capillary glass: 2 vials of 100 pieces per vial: ■■ 3.5” capillaries, Pk100 ■■7.0” capillaries, Pk100 ■■Replacement O-ring kit with standard collet ■■Allen key for replacing wire plunger ■■Needle for backfilling capillaries/micropipettes (30 gauge x 2” length) ■■Universal Adaptor to enable fitting to most micromanipulators Injector Tips Two lengths of borosilicate glass (N-51-A) capillaries are available for use with Nanoject II –3.5” and 7” and are ready for pulling to the required tolerance. Once the tips are pulled, they must be “backfilled” with oil (or other non- compressible fluid) before attachment to the injector. Silicone or mineral oil is frequently used for this purpose. Backfilling is performed using a 30 gauge x 2” needle and a syringe. The precise operation of the Nanoject II depends greatly on the use of tips prepared from the specific glass provided. For this reason, it is recommended that only Drummond microcapillaries are used. Accessories The injector head should be mounted on a micromanipulator or stereotaxic unit using the Universal adapter supplied in the kit. The Marzhauser MM33 micromanipulator is a popular, manual model equipped with high precision and stable cross-roller bearings, which work constantly without any noticeable wear even after many years of intensive use. The MM33 also has a number of ergonomic benefits. The control knobs for all three axes are arranged at the same level so that it can be easily operated without looking. In addition, the operational controls are at the back of the unit, allowing several devices to be easily installed side by side. A support base is available for the MM3 micromanipulator and is also compatible with other brands. For convenient hands-free operation, an optional foot switch can be used to control the Nanoject II remotely. 3-000-024-R 3-000-025-SB
