The ESU 6 Electrolyte Staining Unit is a component of the MicroGraph System, used for creating high-quality cross-sectional images of crimp connections and other samples.

The MicroGraph System examines cross-sectional crimps much faster than conventional methods. The ESU 6 Electrolyte Staining Unit allows users to quickly and safely stain a pre-cut cross-section sample for further analysis.The innovative electrolytic staining solution, which has a pH level of 7 (the same as water), makes handling safe and requires no special equipment or training. A built-in staining indicator glows according to the staining process”s strength, giving the operator instant feedback on its effectiveness. Multiple staining pen sizes are available for different sample sizes. The ESU 6 can be used for a range of applications, from crimp cross-sections to welded samples.
