Description

This solution can be used at a number of different strengths dependent upon the degree of sample grinding & polishing.

• For polished samples (3 μm diamond or finer), micro-etch with 2% Nital
• For a ground sample (600 grit or finer), macro-etch with 5% Nital
• Use 10 to 15% Nital for macro etching on ground surfaces.

Please Note: Etching rate is increased, sensitivity decreased with increased Nital concentration. So please choose the Nital concentration appropriate to your needs.

Swab for between 5 and 60 seconds -check result by eye.
