Description and Specification
Introduction
Biological specimens intended for investigation in a scanning electron microscope
must be dried before being introduced into the microscope to allow the specimen to
be imaged. If specimens with water content are dried, tangential forces, caused by
surface tension of the water, destroys the structures of the specimen as mentioned in
the previous chapter.
Critical point drying with the EM CPD300 is the optimal method to prevent the
damaging effects of the above-mentioned forces by bringing the liquid to the gas
phase without boundary crossing.
