Potassium dihydrogénophosphate, anhydre, poudre cristalline blanche réactif de culture cellulaire
Potassium dihydrogénophosphate
Storage: Room Temperature, desiccate
Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic 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.
Potassium phosphate monobasic is typically used as a component for a wide variety of media used in the culture of microorganisms. It is widely used in molecular biology, biochemistry, and chromatography. It is a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.
