Microm cryostat is an open top model.
It is a precision instrument designed to cut uniformly thin sections of a variety of materials for detailed microscopic examination.
Chamber temperature varies from +50 down to -300 C. For light microscopy,
where magnifications can reach up to 1,800 x, the thickness of a section can vary between 1 and 10 microns (thin sections).
For electron microscopy, where magnifications of several hundred thousands are possible,
the thickness of a section is usually of the order of 10 nanometres (ultra-thin sections).
The cutting action which can be either in a vertical or horizontal plane is coupled with the
advance mechanism so that the material holder is moved after each cut.
