Description
The procedure of critical point drying is an efficient method for drying delicate samples for SEM applications.
It preserves the surface structure of a specimen which could otherwise be damaged due to surface tension when changing from the liquid to gaseous state.
The Leica EM CPD300 critical point dryer dries biological specimens such as pollen, tissue, plants, insects, as well as industrial samples, like Micro Electro Mechanical Systems (MEMS) or Micro fluids and gels in a fully automated and controlled process.
