Narishige IM-400 Electric Microinjector

Narishige IM-400 Electric Microinjector


  • Gas input port for ø6mm diameter hose.
  • Gas output port for ø2mm diameter tube.
  • Gas pressure Injection/Balance pressure 0 ~ 0.5MPa.
  • Power supply AC100V ~ AC240V, 50/60Hz.
  • Flushing pressure 0.4 ~ 0.7MPa.



The Narishige IM-400 Electric Microinjector is ideally suited to DNA micro-injection. By setting the time and pressure before injecting, it is possible to deliver very small volumes with great precision. Operation is straight-forward and achieved via touch panel controls with a memory function that can store user settings.

Note that a compressor or cylinder (air, nitrogen, etc.) + regulator are required to use this device. The IM-400B is a suction unit for the Narishige IM-400 Electric Microinjector. This suction unit enables suction and filling via the pipette tip.
