The first experience with a low voltage electron microscope
Nebesářová, Jana
The low voltage electron microscope LV EM 5 manufactured by Delong Instruments is described and methods of preparation of biological specimens for the observation in this microscope are briefly evaluated. LV EM 5 is a unique apparatus that could replace in medical and biological research laboratories high volatage transmission electron microscopes.
The first experience with the specimen preparation for low-voltage transmission electron microscope
Nebesářová, Jana ; Vancová, Marie
The low-voltage transmission electron microscope, working in the TEM mode, requires ultrathin sections with a thickness 20-30nm. This demand brings problems with a section cohesion caused by insufficient resin infiltration and with a chatter caused by unequal thickness of the section. The contrast of unstained biological specimens in LV TEM is comparable with the contrast obtained in HV TEM of stained specimens.
