The Narishige IM-11-2 Pneumatic Microinjector allows suction and injection of a microsample with high precision and operability comparable to oil hydraulic injectors. Equipped with a coarse-fine coaxial control knob, the microinjector enables both coarse and fine movement operation. Compared with existing pneumatic injectors such as the IM-9C, the IM-11-2 has substantially improvement in relation to the amount of pressure generated for each knob rotation, enabling finer and more powerful control.

The IM-11-2 is free from concerns related to air bubble entry into the micropipette when fitting.

An easy-to-insert fitting mechanism is incorporated in the tubing connection linking the microinjector to the injection holder, improving maintenance and cleaning, including the removal of broken pipette fragments.
