 Ultimately I use latex gloves because I often use acetone which rapidly eats nitrile gloves. ​ The above thumb picture was caused by acetone weakening a glove and subsequently causing nitric acid exposure. Ultimately I use latex gloves because I often use acetone which rapidly eats nitrile gloves. ​ The above thumb picture was caused by acetone weakening a glove and subsequently causing nitric acid exposure.

 +===== Compatibility =====

 +Always test materials for compatibility before assuming that it will play well with nitric acid, especially the fuming variety. ​ In general, oxidizers, organics, and bases react violently with concentrated nitric acid.  Some key materials:
 +  * Alcohol: reacts strongly, even at 70%
 +  * Acetone: less strong reaction than alcohol, but fuming will self heat leading to explosion
 +  * Nitrile: eats through
 +  * Latex: eats through
 +  * PTFE: teflon'​s nearly invincible so mostly no reaction. ​ However, some reactions self heat enough to cause it to decompose. ​ Particularly can be an issue when decapsulating ICs as it produces HF which is not only toxic but also etches the dies
