Injection volumes
WPI™s microprocessor-controlled Nanoliter 2000 uses direct piston displacement. By either pushing the injection button on the control box or pressing on the optional footswitch, a calibrated volume will be smoothly injected. The process is quiet and vibration free. Capillary filling and injection speeds are 23 nL/sec and 46 nL/sec (emptying speeds are 92 nL/sec and 230 nL/sec). Maximum fluid ejection is 5 µL. Each unit comes with sufficient glass to pull at least 300 tips. Glass is 1.14 mm O.D. (nominal) and 0.5mm I.D. By setting the DIP switch, the injection volume can be changed from 2.3 to 69.0 nL in 16 steps. Up to 100 injections may be triggered per filling. Since the volume of a normal Xenopus oocyte is about 500 nL, the instrument has the capability to inject from less than 1% to over 10% of the total volume of the oocyte in one preset step increment.
Included with pump
Included: 1 vial 3.5 in. capillaries (100); 1 vial 7 in. capillaries (100); replacement "O" rings; Allen wrench; MicroFil™ MF34G backfilling needle; and two sample pre-pulled micropipettes.
Smart controller
SYS-MICRO4, an optional microprocessor-based controller, can provide an "intelligent" and easy-to-use interface to up to four Nanoliter Injectors. Operating parameters are set with the membrane key-pad and LCD display. From the keypad the user can set pump to infusion or withdrawal mode, enter the volume to be infused or withdrawn, and rate of delivery, as well as synchronize the starting and stopping of a combination of Injectors. User parameters can be stored in the device's "non-volatile" memory for instant recall when the unit is powered on. An optional footswitch can be plugged into a connector on the rear of the controller for "hands free" start/stop operation. An RS-232 port on the rear of the controller can be used to connect it to a computer for use with computer control programs.

The following images show various setups using the Nanoliter 2000. Keep in mind that parts are interchangeable. For example:
- M10 or the M9 magnetic base could be used.
- PZMTIV microscope could be used instead of the PZMIII.
- M330l
or the KITE micromanipulators can be used, and these micromanipulators
can be placed on either side. (Keep in mind, though, If you wanted to
use a KITE on the right side of the setup below, you would order a
KITE-R (right hand), or if you want an M3301 on the left side, you
would order an M3301-L.)
- 5479 or 5052 magnetic bases are virtually interchangeable.
- One or two Nanoliters, one or two UMPIII systems, or one Nanoliter and one UMPIII may be used, as desired.
