With a lower coefficient of expansion, the WR-6 Three-axis Water Hydraulic Micromanipulator provides precise movement while minimizing drift. It includes both coarse and fine manipulation modes with a manual coarse manipulator for each axis. The drum type control unit has a large handle for precise operation and high linear reproducibility. The design has been focused on precision of movement and stability over long periods of time. The WR-6 Three-axis Water Hydraulic Micromanipulator is outstandingly versatile: when setting up, it is attached using the bar, but independent setup using a magnetic stand is also possible, as is attachment to the side of the microscope stage with an adaptor.
