Research Micro-Injector

Picoliter Microinjector

The PLI-100A picoinjector reliably delivers injections from femtoliters to nanoliters through micropipettes by applying a regulated pressure for a digitally set period of time.

Femtoliter to microliter injections
Digital readouts for injection count, time, and pressure
Reliable optically encoded circuit for setting injection time
5 pressures: inject, balance, clear, fill, and hold

Details
Whether you need to do large injections into capillaries or very small injections into mammalian nuclei, the PLI-100A is up to the task.

Pressure to the pipette is controlled precisely through a multi-turn regulator and is reported digitally for reproducibility. Injection time is set using an optically encoded circuit that permits both fine and coarse settings from a single control knob. System timing can be controlled in three ways: push button, foot switch, or external trigger.
Unique Pressure Capabilities

The PLI-100A features three positive and two negative pressures.
The three positive functions allow the user to:

Inject - Inject picoliter to nanoliter amounts of fluids
Balance - Apply a balance pressure to prevent backflow into the micropipette following an injection
Clear - Clear a micropipette of material that is blocking the tip

The two negative (or vacuum) functions allow the user to:
Fill - Fill micropipettes from their tips
Hold - Provide a means to secure and manipulate a cell using holding pipette.
