Microinjection system

The MIS-EM is a micro-valve plug-in system for the MM3A-EM micromanipulator. It enhances your system by allowing you to microinject various liquids and gases onto your samples in low-vacuum SEM.

The unique combination of precision manipulation and controlled microinjection has attracted a lot of interest in the MIS-EM since its launch. In addition to ground-breaking experiments with fluids, it is also possible to work with non-condensing gases.

The plug-in tool can be quickly and easily retrofitted to your existing MM3A-EM micromanipulator.
