Description

Description

Applications
Potassium phosphate is typically used as a component in the preparation of phosphate based buffers. It is convenient stock solution for making phosphate buffers. The pKa of 6.82 (25 C) for phosphate buffers make them a universal buffer for biological applications such as cell culture media, column eluent solutions and reagents used in molecular biology. Specific applications include buffers for protein purification, bioprocessing and diagnostic reagent production. Potassium salts are used where sodium content needs to be minimized or controlled.

Solubility
Fully miscible in water. Insoluble in ethanol.

Notes
Stable under recommended storage conditions. Store in cool, dry conditions in well sealed containers.
