Sample Preparation Tools
Samples destined for examination and analysis by scanning microscopy come from two different sources. Many specimens are sent from established laboratories that, although fitted with the appropriate equipment designed for the study of all aspects of the particular discipline, may lack the facilities for microscopy and analysis. For example, a materials science laboratory would include a furnace, whereas a biological laboratory would be equipped with an ultra-microtome, although both types of laboratory would contain light microscopes and balances.
The other sources of specimens are those collected directly from the natural environment or from manufacturing facilities and commercial and public centers that lack any equipment for scientific enquiry. Thus, clothing for forensic study, a failed oil pipe, or a newly discovered meteorite require collection and transport to a facility for preliminary treatment before they are prepared for microscopy.
There are two types of...
