In the scanning and transmission electron microscopy laboratory, there are two main microscopes and other equipment necessary for sample preparation, such as an Auto Fine Coater, a Vacuum evaporator, and an ultramicrotome.
The transmission electron microscope (TEM) can be used in many scientific fields, from medicine to material science. Sample preparation in this case is a very demanding process, not only in terms of time. During the preparation of the sample, it is necessary to cut it into very thin sections; therefore, there is an ultramicrotome in the laboratory, which can also be used separately for other purposes. The ultramicrotome has many advanced features, such as section counting, automatic slice thickness 10 µm, slice can be set from 5 nm, automatic feed 200 microns, manual feed 50 mm.
Samples when using a scanning microscope (SEM) can be large (up to several cm). Sample preparation is much simpler than using TEM. In the case of an electrically conductive sample, no further treatment is necessary. Non-conductive samples must be made conductive. For this purpose, there are two other devices in the laboratory. The user can thus choose whether to gild or carburize the sample.
