General description

Useful in the pH range of 7.0-9.0. Has a pKa of 8.1 at 25°C.
Widely used biological buffer (absorbance: ≤0.05 at 260 nm and 280 nm). Useful in the pH range of 7.0-9.0. Has a pKa of 8.1 at 25°C.

Warning

Toxicity: Standard Handling (A)

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.
