This compact micromanipulator combines many features that have made it one of the most popular items available for electrode placement. Weighing only 650 grams, this instrument incorporates X,Y and Z motion controls on the same vertical plane (all within 8 cm), a feature that simplifies movement and increases compactness to allow side by side use of several units if desired. Calibrated vernier scales allow positioning to 0.10 mm with micrometer reading of 10 micron (with estimate to 5 micron) on the X-axis fine adjustment.
