Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic and tribasic. Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
Application Notes
Potassium phosphate dibasic is widely used in molecular biology, biochemistry, and chromatography. It is typically used as a component for a wide variety of media used in the culture of microorganisms, also as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.
