Product Description

Potassium phosphate occurs in several forms: monobasic(KH₂PO₄), dibasic(K₂HPO₄)and tribasic (K₃PO₄). 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 monobasic is widely used in molecular biology, biochemistry, and chromatography due to its high buffering capacity. It is a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate. It is also used as a component for a wide variety of media used in the culture of microorganisms.
