Biologichem Tris, Ultra Pure, Molecular Biology Grade has been used as a buffer in a wide variety of applications, including biological systems. Tris buffer solutions at a wide range of pH are generated using Tris Base and hydrochloric acid, or alternatively with Tris Base and Tris Hydrochloride in a defined ratio and concentration. The use of solid Tris Hydrochloride avoids using more hazardous hydrochloric acid, and allows a more precise ratio to be measured to achieve a specific buffer pH. Tris Base is also used as a primary base standard due to its purity, stability and high equivalent weight. It can be dried at a relatively high temperature (100°C) and is not hygroscopic.
