Webinar: State of the Art Critical Point Drying

Specimens which can be damaged due to surface tension when changing from the liquid to gaseous state need special treatment during sample preparation. Critical point drying is an efficient method for drying such delicate samples for SEM applications because it preserves the surface structure.

Before drying, many biological samples are additionally prepared through fixation and dehydration and then coated after drying with a metal such as gold, platinum or palladium to make their surfaces electrically conductive for the SEM analysis. If the surface structure is altered during the drying processes the results of the following SEM application will provide incorrect results.

In the past the critical point drying was a time consuming process with low sample reproducibility due to the manual operation.

This webinar will show you how the Leica EM CPD300 dries delicate biological or industrial samples in a fully automated and controlled process to preserve your samples for subsequent treatment and analysis.

Watch this webinar, if you are responsible for

  • sample preparation of delicate biological specimens like pollen, tissue, plants, insects
  • sample preparation of industrial samples for MEMS (Micro Electro Mechanical Systems) applications
