Application

The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
Tris Hydrochloride is a commonly used biological buffer which is also referred to as Trizma HCl. Tris as a buffer has very broad usage in biological systems such as diagnostics, downstream purification and cell culture. The pKa of Tris is 7.77 which corresponds closely to a physiological pH of 7.36.

Tris HCl s used in biopharmaceutical buffer formulations (both upstream and downstream), electrophoresis separations and diagnostic reagent formulations. Tris HCl is especially useful in downstream purification processes.
