Application: In biological experiments, it is an important PH stabilization reagent, usually select the appropriate weak acid and its conjugate base mix to get the appropriate PH value. Most biological reactions occur under neutral conditions, the general PH is selected between 6-8, and the effective buffer range of the buffer is also required between 6-8. In addition, the acid-base form of the buffer is required not to chelate with some metal ions. BES buffer range pH6.6 ~ 8.0.
