Description générale

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!

Application

Potassium phosphate monobasic has been used in the preparation of phosphate buffer and phosphate buffered saline (PBS). It has also been used in the preparation of PEG1000 (polyethylene glycol)/potassium phosphate aqueous two-phase systems (ATPS).

Caractéristiques et avantages

  • Increased efficiency – Eliminate time and effort of loosening hardened powders
  • Safety – Avoid risks of using tools of force to break up clumps
  • Economy – Faster preparation and solvation increase productivity and reduce costs
  • Assured quality – Excellent, expert-tested quality with no anti-caking agents
  • Flexible volumes – Available from research amounts to scale-up quantities
