MDO-974 is motor-driven oil-hydraulic micromanipulator suitable for in-vivo experiments on middle-sized animals, mainly NHP primates. Based on the manual oil-hydraulic mechanism of MO-97, the hybrid model installed with stepping motor enables speed control as well as greater driving precision, which are impossible to be performed by manual model. As a merit of hydraulic part that originally required no electricity, the hydraulic-tubing line keeps some distance away from motor to animal's head, so that the sound or noise from the motor would be suppressed on the experiment. Operational setting for drive is absolutely easy to do, which is completed by entering speed directly, or entering distance and time. The range of drive speed is set as 0.1µm/s to 500µm/s. The speed can be changed on the way to target, so you can make the electrode closer to the target with a fast speed, and then change it to slower speed as final small-step approach. The closed chamber is equipped with acrylic XY stage which control knobs drive 18mm on each axis.
* Distance between the control unit and motor unit can be extended from original 2.9m(9.5ft) in total to 7m(28.2ft) by MD-DCE-7 (sold separately).
* Palm-sized compact controller MD-OH-1 (sold separately) is available.
