  • Q:

    How long after opening are pH solutions 4, 7 and 10 good for?
    Asked on 7/25/2012 by Luci

    • STAFF EXPERT

      A:

      Due to variables in handling and storage conditions, it is impossible to certify a shelf life on opened containers. Expect at least 30 days, but following basic practices to ensure the bottles are free from contamination will extend this period. Periodic retesting of the solution will help confirm its stability.
