PMI-200 Pressure Injection System (CORNERSTONE Series)

with VACUUM Pipette Filling

Air pressure micro injection of substances into cells (such as Oocytes) or extracellular space (pressure Iontophoresis)


The PMI-200 is a self-contained, rack mountable cellular injection system for use with an external source of air. Repeatable pressure and precise timing enable the injection of accurate amounts of material injection into cell after cell, an ideal Oocyte Injection system. The 15 PSI injection range is particularly useful for small, precise volume injections.

To prevent backfilling of the pipette when Injection is not taking place, a second pressure regulator is available to set to a RETAIN or Hold pressure.

The inclusion of the unique VACUUM FILL pathway allows you to easily fill pipettes.

The PMI-200 is designed to provide all the capabilities needed for pressure micro injection from picoliters to milliliters with precise pressure and time regulation.but at a price every lab can afford.
