Product Description

Tris

Application Notes

Tris is an excellent biochemical and biological buffer for all applications where ultra high purity is required. 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.

Usage Statement

Research Use Only (RUO). Ready for CE IVD labeling of clinical applications.
