Adler’s Reagent, 500 mL



Adler’s Reagent is an etchant for high alloy, corrosion-resistant steels, Co or Co-Al alloys, such as Inconel 625 or Hastelloy C-276. It can also be stored.


User Instructions:

  • Some crystals will form at the bottom of the container during winter months. To restore for use, place the bottle in a hot water bath until all crystals are re-dissolved.
  • Your alloy sample has to be mirror polished using alumina slurry (0.05 micron) and etched as soon it’s cleaned and dried without any delay. Otherwise, the metal surface will passivate.
  • Immerse or swab the sample a few seconds to a minute.


Nalgene® Leakproof Bottle, HDPE.
