일반 설명
Potassium phosphate monobasic (monopotassium orthophosphate) is a water soluble inorganic salt. Its standard enthalpy of formation has been reported to be −376.1 kcalmol-1. It acts a starting material in the synthesis of potassium metaphosphate.
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!
