    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 6-8),
    so the buffering range is required to be in PH 6-8. 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.
