Product applications: In biological experiments, it is an important ph-stability reagent, usually choosing the appropriate weak acid and its conjugate base mixture to obtain the appropriate ph value. Most biological reactions occur under neutral conditions, the general ph is selected between 6-8 and the buffer effective buffer range is also required between 6-8. In addition, the Acid-base form of the buffer is required not to occur with certain metal ions chelation.
