Cross Section Polishing Made Easy with the CP-8000+

The CP-8000+ from COXEM is a sophisticated sample preparation tool that helps etch a cross-section of a sample with the help of an argon ion beam. This process prevents structural damage and physical deformation and does not need chemical processes that are hard to perform.

Additionally, the system streamlines the cross-sectional analysis of the sample by processing large areas ranging from tens of um to several mm.
