### Phenom ProX SEM 

 

The **Phenom ProX Desktop SEM** is great for imaging and qualitative analysis. There are two types of sample holder, a standard holder and a charge reductive holder. Both sample holders fit samples up to 1 inch in diameter. The charge reductive holder is useful because it can be used in lieu of C coating for most cases, the trade-off being lower resolution imaging.
