Descripción del producto

English Name:1, *-Bis[Tris(hydroxyethyl)methylamino] Propane Molecular Formula:C*1H*6N2O6 Molecular Wt: **2.*4 Description:White crystal powder Assay≥*9.0% PH(0.5% aqueous):*0.***1.0 Enterprise Standard Application: it is an important PH stable reagent in biotic experiments. Appropriate PH is obtained by mixing mild acid and its conjugate base. Many biological responses happen in neutral condition (usually PH **8), so the buffering range is required to be in PH **8. In addition, the form of acid-base of buffer should not chelate with some metallic ions. Characteristics of biological buffer: 1, Strong water-solubility; 2. Compatibility of the acid-base dissociation balance; 3. Low membrance penetration rate; 4. Low metal chelating ability; 5. High chemical stability; 6. Low absorption in ultraviolet and visible region.
