Microinjector with internal pressure source, uPUMP

• High precision for reproducible injections – microliters to picoliter
• Built in compressor eliminates need for external pressurised air system
• Touch screen display and control knob with intuitive user-interface
• Injection Counter
• Injection can be triggered manually using the touchscreen, by foot switch or by a computer-controlled TTL pulse
• Small footprint takes up very little bench space

The µPUMP has a built in pressure supply making it an ideal choice when it is going to be moved between benches and labs.

Designed to simplify intracellular injection and a variety of other microinjection tasks, the microPUMP uses carefully regulated air pressure for injecting cells with fluid. Injected volumes range from picoliters to nanoliters. The port supplies positive pressure for high-pressure ejection. The pressure port maintains a low positive "compensation" pressure to the injecting pipette between injection pulses to prevent fluid uptake through capillary action.

Timing, injection pressure and compensation pressure are adjusted independently using the touch screen interface and control knob. Time intervals can range from 2 seconds down to 10 ms or less, depending on the injection pressure setting. The injection pressure interval is triggered by using a foot switch, manually, or a computer-controlled TTL pulse.

The µPUMP offers separate regulated compensation (back filling prevention) and ejection pressures with a precision timing circuit that switches from injection pressure to compensation pressure automatically.

The display provides easy visibility of key data settings including Injector Pressure, Compensation Pressure, Tank Status, Injection Time, Pump Injection Mode and Injection Count.

Applications of microPUMP

• Microinjection of diverse compounds and biomolecules – DNA, RNA, proteins
• Pre- and post-implantation in embryos of various species – mice, rats, monkeys, bovine, pigs, zebrafish, etc.
