| Application: | Sodium sulfite can be used in aqueous two-phase partitioning systems along with polyethylene glycol for the purification of biomolecules. |
| Features and Benefits: | • Increased efficiency – Eliminates time and effort of loosening hardened powders • Safety – Eliminates tools of force used to break up clumps • Ecology – Reduces waste as it does not stick to the packaging • 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 |
| General description: | Sodium sulfate is an inorganic salt that is commonly used as a reagent as well as a catalyst in organic synthesis. Additionally, it is also used as a drying agent in organic synthesis due to its affinity for water and compatibility with most organic compounds. During the work-up, an organic phase is treated with anhydrous sodium sulfate for the removal of traces of water. |
