Three-dimensional manipulator with added movement capability in the same direction as the pipette

When using this unit to insert a pipette into the cell, operators can make further movement in the same direction, which minimizes the chance of damaging the cell. This one-axis oil hydraulic manipulator meets that requirement and can also be used as an add-on manipulator. A compact drive unit is installed on the tip of the ball joint, giving this model the same high accuracy as a general oil hydraulic micromanipulator.
