Critical Point Drying Method
Drying water-containing biological and material specimens in air or under vacuum
can drastically alter their structures or even destroy them completely by tangential
forces, caused by surface tension of the water (A).
The surface tension is a quality of surfaces between a liquid and a gas and the
tangential forces appears by boundary crossing from liquid to gaseous phase.
