Evactron SoftClean system and accessories

The Evactron SoftClean system extends the ability to pre-clean specimens, specimen mounts, and holders with the proven downstream plasma ashing process before examination in the chamber insuring high image quality. The Evactron SoftClean Chamber can also be used as a specimen storage system, keeping samples in a clean environment.

The downstream plasma process used in the system is gentle and effective at removing hydrocarbon contamination where sputter etching by other plasma cleaners can damage specimens through exposure to energetic ions and heat. The system uses reactive gas radicals to remove hydrocarbons from specimen surfaces by chemical etch, preserving critical sample fine structure. This downstream etching process breaks down residues into smaller molecules such as CO2, H2O and CO, which are easily pumped out of the chamber.

Electron microscope image quality is greatly improved by the removal of hydrocarbon contamination from microscope chambers and from specimen mounts, specimen holders, and the specimens themselves.
