MDO-974A is motor-driven oil-hydraulic micromanipulator suitable for in-vivo experiments on medium-sized animals. Based on the manual oil-hydraulic mechanism of MO-97A, this hybrid model, which incoporates a stepping motor enables speed control as well as greater driving precision, impossble under manual control.  Use of hydraulic-tubing allows distance between the animal’s head and the motor, reducing the potential impact of sound or electrical noise during driving. Drive settings are easily adjusted and can be made by entering speed, or distance/time. The drive speed range can be set between 0.1µm/s to 500µm/s. The speed can be changed while moving, so you can reduce the speed as you get closer to the target site. The chamber is an open-type that is designed to accommodate multiple drive units and use with grid.

  • 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.
  • Grid for the open chamber is available by customized order.
