The STA tool is a tunnel current sensor for the MM3A-EM micromanipulator system and LCMK-EM plug-in. It enhances your system by providing a simple, accelerated and secure method for approaching the surface of conductive samples.

The STA greatly reduces the risk of damaging the probe tip and the sample when approaching a region of interest, even for inexperienced users. It also offers a valuable time reduction thus increasing throughput.

Your existing MM3A-EM micromanipulator system can be quickly and easily upgraded for use with the STA.
