手動系列 MM33-series A reason for its popularity is ergonomics; the user-friendly operating knobs for all three axes are aligned in one plane so that “blindfold” operation of the MM33 is possible within the shortest of times. Moreover, the operating elements are not at the side, but at the back, so that other pieces of equipment can easily be installed next to it.

The micromanipulator DC 3K is made for motorized or manual movement in all three axes (X-, Y-, and Z-axis) which makes it a valuable tool for numerous intracellular applications. The manual part of the DC 3K is equivalent to the MM 33 with additional Z-axis-stop. The motorized action ensues by way of three fine positioning slides with built-in DC motors and micrometer spindle.

2) SM-series The micromanipulators of the SM-series are equipped with stepper motors that in conjunction with the MCL control electronics makes smallest steps of down to 0,01 µm possible. These minute single steps allow for vibration- and back-lash-free operation. The very compact construction of the SM 3.25 makes its mounting onto the stage plate of a microscope practicable.
