•Pressure Input: 0-150 psi
•Pressure Output: 0.3-90 psi

Intracellular injection

Repeatable microinjection in volumes ranging from picoliters to nanoliters. Separate ports supply positive and negative pressure - positive pressure for high-pressure ejection, and suction for supporting the cell or for filling the pipette from the tip. A second pressure port maintains a low positive "holding" pressure to the injecting pipette between injection pulses, to prevent fluid up­take through capillary action or diffusion. Timing, ejection pressure, holding pressure, and suction are adjusted independently by control knobs and indicator gauges on the front panel. Injection pressure is controlled by a 20-turn regulator on the front panel. A built-in timing circuit allows precise control of the amount of time that the injection pressure is applied to the output port. Time intervals can range from 10 seconds down to 10 ms or less, depending on the eject pressure setting. The injection pressure interval can be triggered manually on the front panel, by footswitch, or by computer controlled TTL pulse. A 5 volt monitor output provides a logic-level pulse for your computer or other monitoring device.

PV820 Features

Separate regulated Hold and Ejection pressure, used to maintain a low pressure in the pipette between injections to prevent unwanted fluid uptake by capillary action or diffusion. A precision timing circuit switches from Eject pressure to Hold pressure automatically, once timing has been set. Although regulated vacuum is not provided in this model, suction can be provided by connecting a vacuum source to the vacuum port on the rear panel. Suction is then available through the pressure ports.
