The PLI-10 Pico-liter Injector is designed to provide controlled delivery of picoliter to nanoliter volumes of solution through a glass micropipette. The PLI-10 is ideal for applications such as neuronal tract-tracing, delivery of pharmacological agents in vitro, and Xenopus oocyte injection.
Finally, references to individual control settings are specified in italic type. Special comments and warnings are presented in highlighted text. Any other formatting should be apparent from context.

Xenopus oocyte injection. These ‘large volume’ injections (10 pl to greater than 100 pl) are common for many applications that do not require multiple pressure settings. As such, the PLI-10 is an effective, low-cost alternative to our more elaborate pressure ejection systems (e.g., the PLI-90 and PLI- 100).
M. PRESSURE INPUT (P ) connector: This connector is the input for the compressed gas. 75 PSI is the recommended input pressure; maximum input pressure is 105 PSI. Warner Instruments • 1125 Dixwell Avenue, Hamden, CT 06514 USA (203) 776-0664 • (800) 599-4203 • Fax (203) 776-1278...

Pushing the foot switch triggers an injection for the preset time and pressure values displayed on the instrument front panel. Warner Instruments • 1125 Dixwell Avenue, Hamden, CT 06514 USA (203) 776-0664 • (800) 599-4203 • Fax (203) 776-1278...
SETUP AND OPERATION The PLI-10 is provided with input and output hoses for gas handling and a foot switch for triggering injections. Additional requirements include an acrylic pipette holder (see ordering information below) and glass micropipettes. A regulated air/gas supply and a micromanipulator to hold the injection pipette are needed to create a complete microinjection system.
Different strategies have been used to suitably fix the cell in position for successful intracellular injection: Warner Instruments • 1125 Dixwell Avenue, Hamden, CT 06514 USA (203) 776-0664 • (800) 599-4203 • Fax (203) 776-1278...
Extracellular delivery is nearly always “large”. Intracellular injection is often of “small” volumes (but not for frog oocytes). Warner Instruments • 1125 Dixwell Avenue, Hamden, CT 06514 USA (203) 776-0664 • (800) 599-4203 • Fax (203) 776-1278 Rev 090714...
To prevent this from happening, check each connector for tightness by turning clockwise. This will ensure needle valve depression. Warner Instruments • 1125 Dixwell Avenue, Hamden, CT 06514 USA (203) 776-0664 • (800) 599-4203 • Fax (203) 776-1278...
