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 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.
