  1. How does Redi-Dri help keep salts and buffers free-flowing?

    Redi-Dri products are specially handled and the bottle is specially designed to ensure that the product will remain dry without adding impurities or additives to the product. Ensuring that you receive the highest quality material that is easy to handle.

  2. Are there any special storage conditions that must be maintained?

    No, Redi-Dri products can be stored under the same conditions as the equivalent non-Redi-Dri products.

  3. How long will material remain free-flowing after it is opened?

    While the exact amount of time your material will remain free-flowing can vary, this largely depends on the ambient storage conditions and how many times it is opened.
