General description

Redi-Dri™ technology eliminates clumping and the need for complicated procedures to keep your salts free-flowing. Keeping your salts dry helps improve your results by giving accurate measurements and easier-to-handle salts and buffers. Rather than drying your salts in an oven or desiccator or breaking them apart manually, Redi-Dri™ ensures that your salts will remain easy-to-use for months without worrying about anti-caking agents. Even after repeated openings you can be assured that your results are always accurate. Redi-Dri™ saves you time, energy and money by keeping your salts usable for longer!
Sodium phosphate dibasic is an inorganic salt with the chemical formula Na2HPO4. Sodium phosphate dibasic is highly soluble in water but insoluble in ethanol. It is used as a sequestering agent, buffering agent, pH regulator and saline laxative.

Application

Sodium phosphate dibasic can be used as a buffer in the reverse phase HPLC method.
