詳細

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!

特徴および利点

  • 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

その他情報

As a solid, this product is sodium metabisulfite, Na2S2O5. Dissolved in water, it yields NaHSO3.
