Brief description:

This microscope enables you to perform precise, non-contact laser based micromanipulation experiments The MMI (Molecular Machines & Industries ) CellCut facilitates precise and contamination-free dissection of cell clusters, single cells or subcellular compartments from various types of tissues including fresh frozen, paraffin embedded and archived slides, cytospins, smears and even living cells. The system is operated by the MMI software.

Additionally, you are also able to do high resolution imaging of fixed stained and unstained samples and it is also possible to perform complex live cell imaging experiments. The "imaging functionality" is controlled by the Software NIS-Elements (Nikon) which allows multichannel, multiposition, time lapse imaging and complex experiments.
