Scanning Electron Microscopy
The prime objective of the unit is to provide a
dedicated service to all scientists of the Institute. This
well maintained instrument is also providing better services
to other universities and research institutions on minimum
payment basis. The unit has two scanning electron
microscopes: i) Leo 430, and ii) Philips 505. The Leo 430
is equipped with Back Scattered Electrons (BSE) mode
of imaging with mapping and the line scanning at 180 o
rotation. The elemental analysis of the object is possible
through energy dispersive x-ray analysis EDAX (Energy
Dispersive System/EDS). Both microscopes are fitted
with digital image system allowing high resolution,
high magnification imaging of a wide range of
specimens applied to various disciplines, e.g. plant and
animal tissues; plant and animal fossils; earth, material,
leather and chemical sciences; pharmacy; microbiology;
plastic and metallurgical materials; dental and textile
researches, etc. These electron microscopes require
specialized preparative procedures. In addition to the
standard techniques, the unit also offers sample freezedrying
at the critical point for analysis of delicate
material.
