Cryo-Ultramicrotome
Cryo-Ultramicrotome EM UC7/FC7
Method for preparation
Description:
The ultramicrotomy is a toll for sample preparation for different microscopic analysis methods, like TEM, SEM, AFM and LM. It generates ultrathin slices of material. Mostly this method is used on soft materials or biological samples. The section thickness varies between 10 nm and 500 nm.
