MLW-3 Three-axis Water Hydraulic Micromanipulator

This water hydraulic micromanipulator has been developed for patch clamping. Employing the principle of leverage in the drive unit makes it possible to reduce the extent of movement to only 1/5 of conventional models. A water hydraulic system, less affected by temperature changes, is employed in combination with a 1:5 cartridge, which significantly reduces drift to as little as 1/100 of that experienced with an oil hydraulic manipulator. For more stability against vibration, a large, rigid coarse manipulator is equipped, with the UST-1, which can be firmly fixed to the manipulator while maintaining the setting of the pipette angle. Use of a drum type control section, which allows precise operation, makes this model ideal for experiments that require very fine movement and excellent stability over long periods of time.

  • For attachment to the microscope, a suitable adaptor is required (Type C, sold separately).
  • The micromanipulator can be mounted directly on the isolation table.
  • This model can be firmly fixed to any part of the isolation table with GJ-12 thintype magnetic stand (sold separately).
  • AP-14/AP-13-3 patch clamp headstage holders can be attached on the UST-1 solid universal joint, incorporated in the manipulator.

Principle of leverage

Using this principle, the force on the power point can be increased or decreased in relation to the distances between the supporting point and the power and working points ? which enables the MLW-3 to make finer movements (by a factor of 1/5) than by using the conventional drive principle. The equipment is placed at the back of the hydraulic system, reducing drift caused by temperature changes by 1/5, and contributing to a significant improvement in overall stability.
