IM-11-2

Pneumatic Injector

Smooth and comfortable pneumatic control for both injecting and holding sides

The IM-11-2 is a pneumatically operated microinjector that 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. The IM-11-2 has substantially improved on the amount of pressure change per knob rotation, thereby enabling finer and more powerful control.

The IM-11-2 is free from worry about entry of air bubbles into a micropipette when fitting it.

The easy-to-insert fitting mechanism is incorporated in the tubing connection linking the microinjector with the injection holder, making regular care/maintenance so much easier including removal of fragments of broken pipettes.

The IM-11-2 is outfitted with a one-touch pressure relief valve that allows pressure to escape. With the microinjector in the pressure-free condition, shifting the position of the control knob enables volume changes of the syringe inside the microinjector, thereby changing operational responsiveness; a unique feature of the pneumatic microinjector.

Key Features

1. Easy-to-insert/remove tubing connection
   The fitting mechanism permits one-touch simple insertion and removal of the tubing, thereby making regular care so much easier such as removal of fragments of broken pipettes. Incorporates a mechanism that prevents a kink in the tubing from being transmitted to the injection holder, thereby enabling delicate adjustment of the rotation direction of the needle tip.
2. Pressure release with push-button ease
   Outfitted with a one-touch pressure relief valve that allows pressure to escape. Making it easy to adjust interfacial surface in the pipette or the volume of the syringe. 
3. Responsiveness adjustable to your preference
   Pressure changeability in the pipette tip can be adjusted by changing the volume of the syringe, thereby adjusting operational responsiveness according to your preference.
4. Wide range of movement/pressure characteristics
   Through the adoption of a long syringe and a coarse-fine coaxial control knob, the amount of pressure change per knob rotation has increased by approx. 25 times, which helps achieve a wide range of pressure changeability.
