The P-5 micropipette is designed for precise local application of chemicals in extracellular electrophysiological studies. Drug application may be by one of two methods:

1 ) microiontophoretic ejection of charged substances, or
2 ) pressure ejection.

Manufactured under computer control, P-5 pipette blanks exhibit levels of quality and reproducibility impossible to match in handmade pipettes. The P-5 is compatible with any vertical pipette puller that accommodates 3.00 mm diameter glass. P-5 blanks have a solid ball pulling tip and are fabricated from 3.00 mm Kwik-Fil tubing.

All P-5 pipettes work well with our Pressure Ejection fittings. These fittings connect the pressure ejection tubing to the pipette barrels quickly and securely. PI-305A Pressure Ejection Kit contains 20 plastic fittings, an insertion tool, five 5-ft lengths of coloured tubing, a five-valve manifold coupling, six male luer adapters and one male/female luered line.

In addition, our LD-306 prefabricated silver-wire contact leads provide reliable, inert, and secure contacts between your iontophoresis current source and the drug solutions in the side barrels of the P-5.
