    Its good under those conditions. Taylor suggests one year for reagent replacement but some will last indefinitely under good storage conditions. I like to replace the pH Phenol Red yearly, but that is my OCD.

    Thanks Patrick for your reply. I'll use all until finished. I ordered new supply from TFTestkits earlier this month.
