General description

Trizma® base is a volumetric standard produced under rigorous conditions and measured with the highest possible precision. Its content is determined by volumetric neutralization titration using a combined pH glass electrode. The certified value and uncertainty measurement of the standard are in accordance with ISO Guide 35.
Other Notes
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.
