The PLI-90 Pico-Injector reliably delivers a wide range of volumes through micropipettes by applying a regulated pressure for a digitally set period of time. Compressed gas allows the user to deliver desired volumes from femtoliters to microliters while simultaneously holding a cell. Whether you need to do large injections into capillaries or very small injections into mammalian nuclei, the PLI-90 is well suited for your experiment.

Easy to Use
Inject with the touch of a button or a tap of the foot switch — it’s as easy as that!

Reproducible
Pressure to the pipette is controlled precisely through a multi-turn regulator, and is reported digitally for easy repeat. Injection time is digitally controlled in 10 msec steps between 0.01 to 0.99 seconds (and in 1 second steps between 1 to 99 seconds). Pipette tip diameter, and hence delivered volume, are easy determinations once the timing and pressure are known.

Versatile
Deliver volumes from femtoliters to microliters with the same instrument, resulting in a wide range of applications.

Pressure Capabilities
The PLI-90 features two negative and three positive pressure pneumatic capabilities.

The negative, or vacuum functions allow the user to:
1. Fill micropipettes from their tips, reducing wastage of valuable injectables.
2. Provide a means to secure and manipulate a cell using a holding pipette.

The positive pressures allow the user to:
1. Eject precise amounts of fluids.

Selection Guidelines
The PLI-90 is available in two packages: Basic and Plus. The basic unit is supplied with an input and output hose, handle, power cord and instruction manual. The plus unit is supplied with all of the same parts as the basic unit but also includes a foot switch, pipette holder and input hose adapter.
