Compact, versatile and popular micromanipulator.
This is the most popular micromanipulator for stereotaxic instruments and is attached to AP bar of the instrument when in use. Coarse movement units with a long working range are attached to both the X-axis and the Z-axis; the latter also has fine movement units attached. The fine movement handle is positioned for ease use, and jitters from handle operations are not transmitted to the microelectrode tips. Both vertical and horizontal rotation mechanisms are equipped, enabling approaches from any required tilting angle. Easy-to-use scales are provided wherever necessary for operations following a brain chart. This manipulator has a compact yet rigid design, and can be operated with excellent stability in confined spaces.

SM-15M Substage

The standard SM-15 has X- and Z-axis movement units, but no Y-axis movement (i.e. the same direction as the AP frame bar). This single-axis fine movement unit can therefore be placed between the AP frame bar attachment point and the SM-15 body. This enables smoother, more precise adjustment than was possible by the former method of adjusting the Y-axis with the sliding AP frame bar.
