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.
