Critical point drying by use of distilled CO2.
For avoiding specimen contamination with particles or liquid residues from CO2-supply cylinders during critical point drying the carbon dioxide is taken from the gaseous phase. Condensation takes place in the water cooled pipe between supply cylinder and CPD-apparatus. A sufficient flow of liquid CO2 is guaranteed, all solid and nonvolatile liquid contaminations are eliminated.
