설명

기타 정보

Easily compare specifications for Trizma HCl products with the Trizma HCl specification table.

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.
