  • 1.  Premixed Nital Etching Solutions

    Posted 08-29-2023 10:52

    Good morning to all! We are looking for some insight into where we can purchase premixed Nital Etching solutions. Lately we have struggled with our current supplier and wish to pursue some other alternatives. The mixture currently is 70% Nitric Acid and 30 % water. The other we are considering is a premixed 2% Nital Solution for heat treat micro structure diagnosis for the lab. Our goal is to minimize the onsite mixing and have it available to our heat treat technicians on the floor.  I look forward to others resources in this.

    Hello,

    The 2% Nital solution refers to 2% nitric acid in alcohol by volume. Since nitric acid/alcohol mix can explode the mixing has to follow procedure outline in the Metals Handbook on Microstructures. You can buy the 5% Nital premix from Cole-Palmer and dilute it down to any concentration, including 2% Nital, by adding appropriate volume (after doing your calculations) of ethyl alcohol to the premix.

    Adding more info to Ratnesh's suggestion. I saw Cole - Palmer is selling 2% Nital reagent. I also listed Avantor (VWR) and Qatm (Verder Scientific).

    Verder Scientific do customize reagents as customer needs. Our plant in Canada also has the same issue so I know for sure it is out there.

    Thanks,
