Tris Base vs. Tris HCl: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 6, 2024
Tris Base is a common biochemical buffer, free of any counter ions, while Tris HCl is Tris Base reacted with hydrochloric acid, resulting in a chloride salt.

Key Differences

Tris Base, also known as tromethamine, is a primary amine used to prepare buffer solutions in biochemistry and molecular biology. Tris HCl, on the other hand, is the hydrochloride salt form of Tris, created by reacting Tris Base with hydrochloric acid.
