DESCRIPTION
General description
Trizma® hydrochloride is mainly required for preparation of buffer at physiological range of 7.3 to 7.5. The prepared buffer is compatible with biological fluids. It is of importance to laboratories as a standard pH solution.[1]
Application
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. Trizma® hydrochloride has been used as a buffer solution for staining procedure, reduction and alkylation studies and in situ hybridization procedure.[2][3][4]
