The Gatan PECS II is an automated sample preparation system for polishing and coating samples for SEM, SPM, EDS, EBSD, CL and EBIC.

Prepare damage-free surfaces, cross-sections and deposit coatings to protect or eliminate charging.

Prepare damage-free surfaces

Fully automated

Polishing & coating in one pump down

Monitor milling in real time

With a digital zoom microscope.


  • Polish, etch and coat samples without interrupting the vacuum.
  • Etch at voltages as low as 100 V for fast, damage free surfaces.
  • Suitable for samples up to 32 mm diameter.
  • Transfer samples to your SEM/FIB or glovebox without exposure to air (optional).
  • Digital zoom microscope for real-time monitoring
  • Analyse images in Gatan’s DigitalMicrograph software.
  • Easy touchscreen operation.

Optional Cooling Stage

An optional temperature-controlled liquid nitrogen cooling stage is available. Together with Gatan’s patented WhisperLok system, which lets you load and unload samples without venting the main chamber, you can prevent melting and structural changes caused by heat, which can be a problem with conventional milling processes.
